Finishing up my CS spike hawk mod. First I stripped the paint. Then I used files and sand paper, no power tools. 320, 400, 800 grit sand paper on the head. Then I used Super Blue, one coat and left it on about 2 minutes.
I sanded the handle with 220 grit sand paper. I then mixed boiled linseed oil and wood stain, 50/50 mix. I didn't know how that would turn out, but I am very happy with the results. It was a one time application of BLO and stain at the same time, and the finish is exactly what I wanted.
The grooves I put in the head are an attempt to reduce the weight a little bit, and also to provide a better gripping surface when using the head as a tool for scraping, skinning, ect.
I will probably put some kind of leather wrap grip on the handle. I haven't decided what to do about the screw hole yet.
