If you want a quality SHARP knife, I can recomend going to a slaughter house supplier.
You can buy dedicated combat/slaughtering knives, made by victorinox and hold a VERY VERY VERY sharp edge.
RAZOR SHARP EDGE not for the faint hearted. They have a moulded plastic fibrox handle that wont fall off and is non slip.
They can stand being boiled in water. BUT if you do by one treat it like a broadhead they are lethal in the wrong/stupid hands...
If you think your normal knife that slips gives a nasty deep cut, these beauties will cut to the bone and beyond...
SLAUGHTERING knives NOT chefs knives is what you want.

I certainly hope we will, I sure could use a vacation from this silly shit."
