I've got a custome shoppe 110 with the bg-42 blade. I've used it for 2 years to clean deer and rabbits and I noticed after the last deer that I did that the blade has small chips in it. I have never sharpened the blade (it hasn't needed it) and was wondering if this is normal for BG-42. It seems awfully brittle. Also, if I need to sharpen it, will a Lansky do the job? Use diamond stones or conventional?
