Since I have posting images of my little tool around the knife forums, I have gotten a great response. I have been in contact with some local water jet companies to have a larger batch of these tools profiled for me.
I figured I could post up the drawings of the revised tool, so here you go. The actual size image, the specifications are hard to read, so I have made another picture a bit bigger so that the specs are easier to read.
I have been working on a tool for my small survival kit and now think I’m heading in the right direction. I’m a big fan of using ferro rods / firesteel for spark based fire starting and have wondered why the little thin scraping tool that they come with isn’t capable of more things.

Again the primary use for this tool is to scrape ferro rods, but I have incorporated a few other features that makes have multiple uses.
Overall this tool is 3 inches in overall length and has a 1 1/8″ cutting edge. It is a bit thick being 1/8″ and I may move to a thinner steel on the next one. The finger groves fit comfortably on your index and middle fingers. The top of the tool is notched and is where you would use it to scrape your firesteel. It’s actually notched all the way around the tool to assist with gripping as well as adding strength if you were to attach it to a shaft in order to create a make shift spear or arrow. I have drilled some holes through the handle which accomplishes a couple of things, it reduces weight and allows for a corp wrapped handle. I don’t show the cord wrapping, but I was able to get 8′ of 250 test pound single inner strand cordage, similar to paracord just smaller.
Using the tool I was easily able to scrape some fat wood to use as a base for my fire sparking test. I also found some good thin bark which helped to catch the spark and get my fire going. A couple of scrapes with the ferro rod and viola.
First thing was first fire. I also wanted to test the small cutting edge and see what I could get done with a little tiny blade. I cut a small limb of oak and tried to do some bark scraping and notching. I was able to do some basics and made a tent stake without to much trouble. Granted it wasn’t the greatest tool for the job, but it did work and notching was one of my personal requirements. I wanted to at least be able to make small traps with the tool.
Other than trap notching I wanted to be able to skin small critters and switching your grip on the tool and resting the finger notches on your middle and ring fingers I was able to extend my index finger along the very top ridge to create a comfortable grip for skinning. Now I did run into any critters to test this out on, I’m positive it can be done. I did though catch a few trout and it was like a hot knife through butter gutting the fish. No problems there.
As a last ditch weapon the tool can be attached to a stick to create a make-shift spear or arrow. I don’t really recommend this and would probably opt to just make a point stick and not potentially lose my little tool, but it can be done. 
This is one of the areas that will be changed with the next prototype. On this model the butt of the tool is rounded and it should be squared off more. It had no issues when I threw the spear or jabbed it modestly into a tree, but when I really gave it my all and used a lot of force the rounded butt slipped out of the side of the spear.
All in all it was a pretty successful testing demo of the capabilities of the tool and I am happy with the direction it is heading. A few more changes and I think this will be the best firesteel / PSK tool that I will make.
