This Instructable will show you how to add a hatchet function to your Fiskars/Gerber brush knife making it a versatile tool for hiking and bushcraft.

The Fiskars brush knife is a high quality tool for a moderate price available pretty much everywhere.
While it does make up for a big knife it could also do a lot more.
I will try to add some funktions basically making a whole survival platform out of it.

This instructable is written under consideration that not everyone out there knows his tools and how to work them so if you already do... keep that in mind and please be patient.

What you will or might use:
- Protective gear... honestly... I'm not kidding... you're working with a sharp edge and powertools and learning to work with all that cost me dearly in the past because I didn't follow this advice.
Use eye protection, earplugs and gloves
furthermore make sure that your clothes aren't dangling about in a loose manner or they'll get caught in the machinery.

-Beltgrinder with rough- to fine-grit paperbelts
-Anglegrinder with a sandpaper-disc
-Revolving wetstone (If available)
-Fine grit sandpaper (For the finishing touch)
-File (Needed to improve the sheath)

As I pointed out this is dangerous work and I will not take responsibility if you hurt yourself.
You have been warned.

So lets get going :)

P.S. English is not my native language so feel free to correct me if I'm wrong with any words or grammar.

Step 1: Grinding (if Your Its Edge Is Still Fine Proceed to Next Step)

My brush knife has seen some action and needs some work on its edge.
Some work with the anglegrinder and beltgrinder did the trick
<p>Your written English is good but you asked for corrections so...</p><em>Step 1: Grinding (if your edge is still fine proceed to next step)</em><p>I removed an unnecessary word from the sentence above.</p><p>Also the word is whetstone, not wetstone ;)<br>BTW I love my Fiskars brush axe.</p>
<p>I have an unaltered fiskars brush ax and it cut though an 8 inch log well enough.</p>
hmm- well written instructable but I'm not really sure why you feel the need to do this to the lovely gerber/fiskars brush knife! you already have a flat blade and you can cut down trees up to about 4 in diameter with an unaltered blade. And as the blade is fairly light trying to cut anything bigger is likely to damage this nice piece of kit. Also using power tools can be a recipe for ruining the blade- get it wrong and heat it up too much and it's buggered. If you want to cut down large stuff you'd be better off using a heavier blade which is designed for the job.
Good point you got there. <br>Its not the best solution for a job an axe should do. <br>I did have situations however where the curved blade just got stuck or in the way <br>and a rounded blade would have performed better. <br>Since I carried way too much last time I wen't hiking I'm going to leave stuff behind I don't need. For this case the added edge will suit me fine I hope. <br>Maybe I can add some more functions to the brush knife an its handle and sheath. <br> <br>Nontheless: You are right it is no total substitute for a hatchet or an axe in everyday work. <br> <br>
If you have ideas about possible further modifications let me know :)
