Well... HISTORY tells us... 200 years ago, (1700-1800's)
A good sharp knife (as in 1) was an esential part of EVERY Hunter, Trapper, Explorer, Outdoorsmans, kit. It was used (and abused, I'm sure!) every day, for ever chore & task, where something needed cutting. It was strong rugged & dependable. Knives were not something to be cast aside, when they were no longer "sharp". They were a tool that was important to their daily survival. With not much more than a knife, tomahawk, gun, powder, shot, flint&steel, and a blanket, these men ventured into the WILDERNESS, for weeks, months, sometimes years, at a time!!! These men were farther away from CIVILIZATION, than you will EVER be from your truck.
As far as me "poo pooing" your havalon... My good sturdy, sharp knife, will be around longer than you'll be able to get new blades for yours!!! (and mine will still be sharp)
Alas my Brothers, to each their own... If it works for you, that's fine with me. I'll stick with my knife thank you, it's always served me well.
