there has been alot of talk about a busse khukuri. it would seem S7 would be the perfect steel. incredibly strong and much cheaper than infi. it also is more resistant to rust than 5160. the res c handle would be nice for the heavy chopping.
i would lile it 3/8 thick by 16 1/2 to 18 inches long but i was hoping everybody would suggest what would be a good size
