My Attempt at 91mm Bladeless (Hacker Badge Request)
on: September 07, 2016, 11:40:01 AM
It's been a while since I've been toying with the idea of a bladess 91mm multi-tool. Since I've got some leftover parts, might as well go for it.

My idea is based around a SwissChamp. Removing the large and small blade along with the fish scaler, retain the corkscrew and arranging the layers a bit. So here it goes.

The tricky part for this build was to retain the corkscrew. This means making use of the blade's backspring and put in place a metal saw. But this means there should be a stopper at the other end. My approach was to use an extra scissors backspring pictured below.



I've already marked with a Sharpee the area where I need to cut using the metal saw back spring stopper as template. Once marked, took my rotary tool and started grinding. Surprisingly didn't took long. Also did a lot of filing to smooth the edges into desired shape. Below is the result.



Next step was to cut the scissors backspring



Then marked the area where I need to make room for a notch with a sharpee. This is to allow the custom stopper to sit nicely on the blade back spring.



Cutting little by little and doing lots of fitting repeatedly so as to get desired spring tension. And bellow is the result.



And this is how the custom stopper fits.



Since the scissor backspring is about 0.5mm thicker than the blade backspring, and with no access to a bench grinder, I resorted to using a sharpening stone to slim down the stopper. I also initially thought that I would need a washer to compensate for the metal saw thickness. But using a new outer liner (with indentations) solved this.



Metal saw layer now completed with good snap and pop on both implements.

Time to assemble. Nothing really special here as it follows normal practice (at least for me) using tricks already mentioned in this forums.

Below are pics of the assembled layers.



The final layer...



Ready for peening...



And the result, my Bladeless 91mm... Finally...

Nice mod! Neat that the indention meant for the blade works for the metal file with no trouble. Very cool :tu:

This is a very clever and brilliantly executed mod JM - Resulting in a great SA K

And a fabulous step by step - very clear, and consise, with great, top quality photos
You have made me very embarassed about my recent step by step with its crappy photos and verbage  :o!!

A few Qs:
Why could you not make a stopper/rest from the file's original spring (ie less work)? I am assuming that it's too thin for the new spring for the file. 

Knifeless tools are popular for various reasons usually to do with rules legalities etc
But often the rules say you can carry a knife if you have good reason.
So when you said this SAK was destined for your tool box in your car I was puzzled as:
  • Don't you need to have a knife in car tool box eg to cut a hose, zip tie etc
  • Isnt that a 'good reason' to have a blade - So you would be ok with the law

Hi Huntsman, no need to be embarassed... I learned alot from the step by step guides posted by everyone in this forum. It is what got me decided to go ahead with my custom stuff...

Why I used scissor backsprings for stoppers, actually can't remember now...

You assumed correctly. Initially wanted to use the metal file backsprings. But then upon closer look, it was thin compared to the new spring for the file. Will need some spacers or another metal saw backspring. So I looked at other springs I had lying around. It was only the scissors that's about the same width.

To answer your next question, it has a lot to do with laws. Knife laws in Indonesia goes back to the times if Dutch colonization and was made during emergency situation. It hasn't been updated since. No one is allowed to carry knives around "except for good reason". Very gray I must say in the sense that it is subject to different interpretations by different people. That's also why sometimes I only carry the Minichamp.

Hence the bladeless in my car toolbox. And it's not meant only for work on the car. If I need to cut cable ties, then scissors will have to do. If I need to pull out fuses, then I know I can depend on the small vic pliers. If I need to tighten screws then I have some tools ready. Sometimes I would need a multi-tool to do some fixing on my parents house or any other place I'm at.

To me, a SAK is not a knife. It's a multi-tool.  I feel safe knowing I have tools lying around and is always there when I need it.

Sometimes I do carry another SAK or my Spirit. Most often the Yeoman (feeling like a law breaker and risking gettin caught)... Hahaha...

Doing this bladeless project gives me chance to my practice grinding and filing skills. As I had never done this beforehand. I will need this learning curve as I plan to implant 91mm scissors for my 84mm golfer project. My guide for this project is the awesome step by step posted by Syph007. Or was it PTRSAK's?
