In Taiwan, these things are everywhere. It's typically a knife used by students to sharpen pencils. You can get a dozen for around 3 dollars. I'd keep one in my wallet just to have blade on me for instances where I may need a knife

A pair of pliers quickly takes out the rivet holding the blade in

Blade and handle separated

I chose a standard hook and a deforest diamond from Southord, as well as an L rake from a wallet set I got off Budk.

Decided to include a 0.008" feeler gauge to use like a peterson mini knife.

Ground down the handles of the pick to fit into the knife handle and drilled a hole that was the same size as the one in the knife handle


Here's a dry fit with a 4mm screw

Testing of it's functionality. Feedback sucked until I tightened the nut and screw, but that fixed the problem.

Small enough profile to fit my wallet

This is the profile I ground into the feeler gague. The idea is to leave more material than I need on this so that as it inevitably gets bent and chewed up with use it can be ground back and keep using it.

Testing of the feeler gauge/decoder. It works pretty much just as well as the Peterson mini-knife

Riveted together with a 3/16th aluminum pop rivet


Finished product! Perfect for my EDC.
