Victorinox Classic SD vs Leatherman Micra
Written by John Wren|

Choose the Victorinox Classic SD, black, model 0.6223.3B1, for 58 mm, seven functions, and a claimed 22 grams. Choose the Leatherman Micra, model 64380101K, for 10 tools, spring scissors, a claimed 1.8 ounces, and a 2.5 inch closed length. Neither one is the camp knife.
Key takeaways
- 0.6223.3B1 is the black Classic SD, item 06223, 58 mm, seven functions.
- The bullet weight is 22 grams. The details cell says 0.02 kg.
- 64380101K is the gray Micra, 1.8 ounces, 10 tools, 25-year warranty.
- The 6.5 cm parenthesis does not match the 2.5 inch closed length.
Buy the Victorinox Classic SD in black, item 06223, model 0.6223.3B1, when you want the 58 mm keychain knife the bullets size at 22 grams with seven functions and a 25 mm screwdriver tip on the nail file. Buy the Leatherman Micra, model 64380101K, when you want the gray keychain tool the card calls 10 tools at 1.8 ounces, with a closed length of 2.5 inches and a blade the description sizes at 1.6 inches. Both live on a key ring. Neither is a camp knife you can baton, and neither replaces a fixed blade.
Short version. A Companion or an Opinel No. 8 is the knife that cuts lunch. A Wave+ or a Center-Drive is the pliers in a sheath. A ferro rod lights tinder. A filter is water. The keychain tool is the scissors and the screwdriver you still have when the pack is in the car.
The Victorinox card is the Classic SD, black, item number 06223, item name Classic SD, model 0.6223.3B1. The bullets list seven functions: small blade, scissors, nail file, screwdriver 25 mm, key ring, toothpick, tweezers. Dimensions in the same bullets: height 9 mm, length 58 mm, weight 22 grams. Scale material is ABS and Cellidor. The details table prints an item length of 2.28 inches, folded size about 2.1/4 inches by 0.35 by 0.35, and an item weight of 0.02 kg. Fifty-eight millimeters is 2.28 inches, so the length cells agree. Twenty-two grams is not 0.02 kg. Two hundredths of a kilogram is 20 grams. The bullet says 22 grams. Trust 22 grams unless your scale disagrees, and do not average the cells into 21. The UPC on the card is 7611160014344. A different scale color, a Classic SD with a different item number, and a larger Spartan are different knives.
The Leatherman card is the Micra, gray, model 64380101K, part 64380101K. The bullets say 10 tools, spring-action scissors, a nail file, tweezers, and a key ring, at 1.8 ounces. The description prints closed length 2.5 inches and, in parentheses, 6.5 cm, weight 1.8 ounces and 51 grams, blade length 1.6 inches and 4.06 cm. Two and a half inches is 6.35 cm, not 6.5 cm. The details table prints item dimensions 2.5 by 0.5 by 0.8 inches and item weight 51.03 grams. Fifty-one grams is about 1.8 ounces, so the weight cells agree with each other better than the centimeter parenthesis agrees with 2.5 inches. Use 2.5 inches and 1.8 ounces as the card's claim. The warranty line says 25 years. There are two GTIN numbers on the details, 00037447543685 and 00037447676062. Match 64380101K so you do not receive a different colorway or a different generation that shares the Micra name.

| Job | Classic SD 0.6223.3B1 | Micra 64380101K | Buy |
|---|---|---|---|

| A printed blade length | The card says small blade, not a length | Description says 1.6 inches | Micra if you need the number |
| A 25 mm driver tip | Named on the nail file | Not the claim on this card | Classic SD |

Victorinox item 06223, model 0.6223.3B1. Leatherman model 64380101K. A Wave+ is a different tool.
Who should buy the Classic SD, and who should buy the Micra?
Buy 0.6223.3B1 if you want the smaller, lighter keychain and you are honest about the jobs: a package, a splinter, a loose screw that takes a 25 mm tip, a thread, a tick you would rather lift with tweezers than with fingernails. Twenty-two grams is the bullet. Fifty-eight millimeters is the closed length. It disappears on a ring with house keys. The toothpick and the tweezers live in the scales. They are small, they fall out if you flick the knife open over a grate, and they are the reason people keep this model for a decade. Black scales are this card. A printed national-park scale with a different item number is a different Classic SD even when the tools match.
Buy 64380101K if you want the spring scissors and the extra tools, and you will tolerate 1.8 ounces and a 2.5 inch closed body. That is still a keychain, and it is no longer something you forget. The description's 1.6 inch blade is a short edge. It opens a bag and cuts cord. It does not slice an onion for a camp dinner, and it does not baton. The 25-year warranty is Leatherman's line on this card. Victorinox's bullet offers a lifetime against defects in material and workmanship, with electronics at two years, and it says wear, misuse, and abuse are not covered. Neither sentence is a reason to pry with the tip. A snapped tip is abuse, not a defect.
Do not buy either tool as your only knife on a trip where you will cook, feather sticks, or dress a fish. The Companion and the Opinel No. 8 exist because a 40-millimeter-class edge is the wrong length for food. Do not buy the Micra because you wanted pliers. The Wave+ is the pliers. The Micra is the keychain. Do not buy the Classic SD and then expect a bit driver set. The driver on this card is the 25 mm tip on the file.
What the Classic SD 06223 is actually for
Victorinox lists a small blade, scissors, a nail file with a screwdriver, a key ring, a toothpick, and tweezers, and calls that seven functions, at 58 mm and 22 grams, scales in ABS and Cellidor, item 06223. That is a pocket groomer that also cuts. The scissors are the tool people actually use. The blade is for cord and tape. The file is for a nail and for a small screw. The tweezers are for a splinter. If your keys already include a bottle opener and a flashlight, this knife should not also be asked to turn a lag bolt.
The details weight of 0.02 kg is the cell to ignore or to treat as a rounded 20 grams. The bullet is 22 grams. A kitchen scale ends the argument. The folded-size line that reads 2.1/4 inches is the same 58 mm written badly. Height in the bullets is 9 mm. The details height of 0.35 inches is about 9 mm. Those agree. The UPC 7611160014344 and the model 0.6223.3B1 are the reorder pair. A red Classic, a silver Classic, and a Classic with a pen are different item numbers.
Do: open and close every tool over a table the day it arrives, so you learn which end is the toothpick. Don't: put it in a dishwasher. Don't: use the blade tip as a pry. Don't: carry it into a place that bans knives because it is small. Small is still a blade. Check the rule before you clip it to a airport key ring or a school bag.
What the Micra 64380101K is actually for
Leatherman's bullets call the Micra the mini tool with spring-action scissors, 10 tools in 1.8 ounces, built for a tackle box, a pocket, or a keychain, with a 25-year warranty and a key ring so it stays put. The description adds the 2.5 inch closed length, the 1.6 inch blade, and the 51 gram weight. The details weight of 51.03 grams matches that 51 gram line. The parenthesis that says 6.5 cm does not match 2.5 inches. Measure the closed tool. If it is about 2.5 inches, you have the length the inches claim. If a seller ships a larger Leatherman, you have the wrong model.
Spring scissors are the reason to accept the extra weight. They cut tape, thread, a bandage, and a fishing leader cleaner than a short blade does. The file and tweezers cover the same groomer jobs as the Classic SD. The rest of the ten tools are small. Learn them at the kitchen table, not in the dark at a trailhead. A tool you cannot find with your thumb is a tool you will not use. Gray is this card. A different handle color with a different part number is a different Micra even when the tool count still says 10.
Do: oil the pivot once, with a drop, if the tools start to feel dry. Don't: baton, don't pry, and don't twist the blade. Don't: assume 10 tools means pliers that will pull a cotter pin on a trailer. That job is a full-size multi-tool. The Micra stays on the keys.
How to carry a keychain blade so it is still there
Put it on the ring you already check, not on a decorative ring that lives in a bowl by the door. A split ring through the hole on the Classic SD, or through the Micra's key ring, should take a tug. If the tool can slide off, it will, in a parking lot. Keys in a pocket beat keys on a lanyard that swings into a saw or a stove. Take the knife off the ring when you hand the keys to a valet or a kid. Small blades still cut.
Learn the local rule before you clip either knife to a bag. Schools, courthouses, and aircraft cabins often ban blades that would be ordinary on a trail. If you cannot name the rule where you are going, leave the knife in the car or at home. The tweezers are not worth an argument at a door.
Use the right edge. Scissors for cloth, tape, and a bandage. The blade for cord. The file for a nail, not for a bolt. A fixed blade in the pack does the wood and the food. Fire is a separate tool. A keychain knife is a poor striker and a worse wedge. If the only sharp thing in camp is 22 grams of stainless, the camp kit is unfinished.
What actually fails on a keychain multi-tool
The scale tools fail first on a Classic SD. Tweezers and a toothpick launched across a trail are gone. Check that they seat. The pivot fails when grit and no oil make the blade hard to close, and then someone forces it onto a finger. Rinse grit, dry it, one drop of oil. The tip fails when it was used as a screwdriver on a screw the 25 mm tip does not fit. Walk away from that screw.
The model fails next. 06223 and 0.6223.3B1 are this black Classic SD. 64380101K is this Micra. A Cadet, a Rambler, a Squirt, and a Style PS are different tools with different weights. The centimeter parenthesis on the Micra fails as a measurement if you treat 6.5 cm as exact. Use the inches, then a ruler.
The other failure is pretending the keychain is the camp knife. A 1.6 inch blade and a small Victorinox blade lose to cheese, to a carrot, and to a feather stick. Carry the edge that matches the food. Keep the keychain for the job it is actually good at, which is the job you have when your hands are in your pockets and the pack is twenty yards away.
What this comparison is not
It is not a fixed-blade knife, a hatchet, or a pair of pliers. It is not a lighter. It is not a promise that 0.02 kg and 22 grams are the same reading. The bullet says 22 grams. It is not a promise that 6.5 cm and 2.5 inches are the same reading. The inches say 2.5. It is not a legal opinion. Blade rules change by city, and a keychain does not make a blade invisible to a metal detector or to a posted door.
It is not a reason to skip the sheath knife you already know how to use. Match 0.6223.3B1 if you want 58 mm and seven functions. Match 64380101K if you want the 1.8 ounce Micra and the spring scissors. Leave the full-size multi-tool in the pouch if the job is pliers. Leave the Companion in the pack if the job is food.
So which keychain tool should you buy?
Buy the Victorinox Classic SD, black, item 06223, model 0.6223.3B1, when you want 58 mm, a claimed 22 grams, seven functions, and a 25 mm driver tip. Buy the Leatherman Micra, model 64380101K, when you want 10 tools, spring scissors, a claimed 1.8 ounces, a 2.5 inch closed length, and the 1.6 inch blade the description prints. Weigh the one you unpack if the gram cells disagree. Then put the real knife in the pack.
Frequently asked questions
Victorinox Classic SD or Leatherman Micra?
Classic SD 0.6223.3B1 if you want 58 mm, seven functions, and about 22 grams. Micra 64380101K if you want spring scissors, 10 tools, and can live with 1.8 ounces.
How long is the Classic SD?
The bullets say 58 mm closed and 9 mm high. The folded-size line that reads 2.1/4 inches is that same 58 mm. Item 06223 and model 0.6223.3B1 are this black knife.
Does the Micra include pliers?
No. Ten tools and spring scissors are the claim. Pliers that pull a cotter pin are a Wave+ or another full-size multi-tool. The Micra stays on the keys.
Why do the Micra lengths disagree?
The description says 2.5 inches closed and also prints 6.5 cm. Those are not the same length. Measure the closed tool. About 2.5 inches matches the inch claim.
Is 0.02 kg the same as 22 grams?
The details cell says 0.02 kg, which rounds to 20 grams. The bullet says 22 grams. A kitchen scale ends it. Do not treat the cells as two different knives.
Can a keychain knife replace a fixed blade?
No. A 1.6 inch Micra blade and a small Classic blade are for cord, tape, and a splinter. Food and wood belong on a Companion or an Opinel in the pack.
