Looking for a hunting knife. Seems a little overwhelming. My needs are something that can process a moose, hold an edge and wont break the bank. I have my eye on a KOA knife but the two I like are either 3” or 3.5”; are those big enough or would I need something in the 4” range? The benchmade saddle mountain skinner has my attention as well, but the price is pretty high. Any other brand recommendations would be appreciated. Thank you.
