On the recomendation of a few guys on this site ive just bought a bushknife complete with very orange handle and a doubly sharp sharpener.
The knife arrives pretty sharp, and a couple of strokes through a doubly sharp and its like a razor.
Ive been using a 20 year old hand made falcon blade (very worn, but the blade is 4mm thick at the back and very tough) for ages now, but having prepared a couple of rabbits today I am now converted.
The bushknife has a very secure feel to it, the handle is rubber and provides a confidence boosting grip. And like the guys said, you're not going to lose it quickly!
The sharpener is very well constructed, works a treat and feels like a quality piece of equipment - the carbide edges revive old blades quickly and the ceramic edges give that extra bite for preparing animals.
I bought the knife and sharpener for £9.79 and would thoroughly recommend both.
For the price you really can't go wrong and I was very pleasantly suprised at build quality of both items.
