Step 1: Taking your MT apart-

Picture of Taking your MT apart-
2 Take out bolts.JPG
When taking your MT apart, especially for the first time, it is important to remember and note which pieces go where...

Believe me, if you get them messed up your going to be there for a while sorting the mess out.

I prefer to take an A4 piece of paper, and line the parts out in order...
This allows us to simply "stack", the parts back into the chassis of the unit..

Begin by locating the fixing mechanism's, which retain the implements..
On my model I have four small bolts...
Some models have a swing arm locking mech..
Locate it and remove the locking system..


Step 2: Removing implement stacks

Picture of Removing implement stacks
Now we will remove the implement stacks..
Before doing so have a look at how they are stacked, how the finger grips are positioned etc. This will be important when re-assembling the unit...
Take care not to loose the spacer washers if used.

Take the stack out in one piece..
Then line the implements out in the order of the stack..
Write numbers on the paper for reference if needed..

Once we have everying separated, it should be easy to see rust, wear and tear etc...

Excellent idea in making a diagram of all the parts. I just set them out and traced them onto paper. Also, while I had my tool apart, I was able to add the glowing PlastiDip I had made for my own Glowing Tool Handles Instructable.

This is an excellent guide. Must of the times I clean all my tools with WD-40 and never had problems with it. I have never done a guide on how to clean tools, so this article gave me some ideas.
I have reviewed this tool at Best Multi tool so you can take a look at it. Thanks

What Multi- tool is this?

I use WD-40 as a solvent in cleaning, then 3-in-1 or some unlabeled can of silcone spray I found in the basement. Unfortunately, my leatherman was not built to be disassembled. But, I find a stiff toothbrush suitable to clean every nook.

OR, you could send it back to the manufacturer, they will clean, sharpen, replace broken parts and send it back for free. I've done this a couple times.

thats what i did man i sprayed some w-d inbetween my lock knife and it worked forever . i dont know why everybody is hating w-d man i use it fore every thing and it never let me down
Lftndbt (author)  Supercoke6 years ago
Oh the humanity! WD-40 has many a good use, unfortunatley none of which include long term lubrication of moving joints. It is an attractant in nature and as a penetrative lubricant lends its self towards having tiny grit and dirt particles adhereing to it. Sure it works great at getting things moving. That's its job. But long term no, it's not what it is designed for and can down right damage delicate or precision pieces of equipment. Statements like "thats what i did man i sprayd some w-d inbetween my lock knife and it worked forver ." don't really help the cause for "good information" as your "forever" may not be accurate. So how long is "forever"? Here's a little test if you need proof. Spray some Wd-40 in you front door lock mechanism and see how long it takes to jamb.... remember great at first but just wait.... (I advise you do not do that , please.)
WD_40 is Water Displacing formula number 40, it was developed to keep water away from electrical components in salt water environment. it is a Fish Oil based product and is a very poor lubricant over any length of time as it turns into a very pretty light golden colored semi solid, a reapplication renews the original BUT leads to a thicker covering again when it solidifies. About the only way to remove the golden sludge is another application of WD-40 to loosen the older caked on sludge and then clean it all of with a solvent. Use 3 in 1 oil instead of WD-40 it is actually compounded to LUBRICATE unlike WD-40.
I like rotor oil like the kind used in brass instruments, its primary use is for the long term lubrication of moving joints, a little in my knife and a little in my french horn makes life a lot easier
Wasn"t sure where to suggest this but this seems as good as anywhere. For a wunder lube and rust remover you might try Break Free. It's a family staple in our tool room. Good enough for gunsmithing work and really gets into the small places. I brought a rusted chunk of a Victorinox back to life with it.
for your info that same lock knife is the one i take out boating and iv dropedin the salt water and it still works fine and forever is about 6 years

i agree with Lftndbt, wd-40 just rust remover not for lubricate things
well lets see...WD-40 stands for water displacement & it took them 40 tries to get it right but yes i agree it is not meant for long term use(its really meant for rust anyway)
Yeppers! WD40 is good for a quick fix, but is very bad to depend on for long term lube. It turns to gum, IMO.

i think the one thing you might have missed
i do to all my knives and stuff like that is to make sure all the plastic washers are in good shape i broke a couple and replaced them with copper washers that i soaked a bit in oil works great..better than the plastic/Teflon ones cause they don't break theu just wear after a long time

Contact letherman, they will replace or repair it for free. They never have asked me for proof of purchase
Funny thing about being the sole manufacturer of a product, isn't it? That big "Leatherman" logo on the side, and the fact you own it is proof of ownership. I'm not digging at you or anything - just stating the obvious about things with lifetime warranties. Zippo and many brands of tools (Craftsman, et al.) also spring to mind...
proof of ownership is not proof of purchase, alas, regardless of childhood readings of the "possession is 9/10ths" law.
how about finding a 5 pointed bit and drilling a hole in the middle for the post?

Is this what you are looking for?

Five Point Torx Security Bit Set
http://www.mcmelectronics.com/product/22-9795

They are called torx screwdrivers. you can buy them individually at a good tool shop. They are rated by number. Torx 25 Torx 26 etc. I picked mine up for my ryobi brushcutter at a bearing shop. they come with or without the hole in the center to accomodate the pin. About 8 bucks each
I've noticed this too (on my Charge TTi), and sent a fairly strongly-worded (polite, but expressing my amazement) that a company as hacker-friendly as Leatherman would use such goofy bolts. I mean you just know Tim Leatherman has to be a hacker at heart! I share your frustration.

BoneLESS Chicken does not have bones and never will. So stainLESS Steel can stain?

Ok, lame jokes aside, I thought stainless steel would not rust. But that [robably depends on a few factors.

Also I was wondering if you know of any way to make or buy replacment blades for a multi tool. Specifically a Gerber Suspension. I just picked one up and was thinking about trying to replace a few things I wont ever use with something a bit more usefull.
stainless steel "stains less" it is not 100% stain proof of rust proof
Valkyrie1034 years ago
Why bother with all of this when you can just buy a SOG? I have one and it has been through just about everything. I've never had to clean or sharpen it ONCE and it still has its factory sharp blade and zero rust!

Someone mentioned Leatherman tools being stainless. I don't believe so... it's my understanding that stainless won't magnetize, but after a thoughtless and prolonged encounter with a welding magnet my Blast pliers are slightly magnetic. I make sure to use a different tool for electronics. Am I right about stainless and magnetism?
There are different grades of stainless steel. Some rust more readily than others. Tool-grade and some cutlery stainless steels (such as 400 series) have a higher iron content and more carbon, which makes then more prone to rust and magnetism. 18/8 stainless is frequently used for cooking utensils, pots and pans is less likely to rust or be magnetized. Keep your tools clean, dry and lubricated and you will get less corrosion and longer life.
To my knowledge from my Blast, the Leatherman Blast's body is fully constructed of stainless steel. Stainless steel can magnetize but only after prolonged contact with a strong magnetic field. I have frequently covered mine in water for the last 9 months and it is still like brand new.

if you have the swisstool by victorinox like I do, you wont have to worry about rust.
A leatherman's better then a swiss tool.

I lost my original classic Letterman and want to know what model will replicate it best and the cheapest place to buy one.
What tools do you use to get the bolts out?
torx screwdriver
Lftndbt (author)  JMBreitinger5 years ago
He he he, another multi-tool. ;P
My sister once gave me one of those little bitty SwissTek keychain thingies. The first thing I did with it was to tighten the scissors on my Swiss army knife. She didn't understand why I giggled.
