Joss, Many thanks for showing my/your knives, it's very much appreciated and I enjoyed the project immensely. To all those who have posted - thanks for your kind and encouraging words.
The steel I used is "Bohler" Steel (Austrian) K110 equivalent to A.I.S.I. D2. Composition: Cr 11.8 : C 1.55 : V 0.95 : Mo 0.80 :
Mn 0.35 : Si 0.25.
Bohler South Africa no longer carry this steel in sizes suitable for stock removal knifemakers, so I started off with having to split a much thicker bar on the bandsaw and mill it down to 1/4", quite a job but well worth it. They also do my vacuum heat treatment to 59/60 Rockwell C.
The method I use for fine sanding and mirror polishing is best described in my tutorial
www.robbrownknives.com/tutorials/mirrorfinishing/
I used both 14" and 6" diameter contact wheels on these knives and followed the steps outlined exactly. Fine sanding up to 1200 grit before buffing this way is a totally different ballgame to handsanding, it's a lot easier, faster, and sands to a finer finish (unfortunately only suitable for concave grinds). If you can, give it a try.
B.T.W. Nathan, I love your dog - I have a 11 month old bull mastiff.
