Perhaps I am preaching to the choir...however, my Basic 9 has been with me through thick and thin. It was left outside in a heavy rain storm and suffered some rust spots. Then there was the time it got thrown over the side of my boat...lucky as heck to have found it again. I have opened cans of beans with the thing, chopped hardwoods and even butchered a few deer. At least ten people have tried to buy the thing off me. A friend of mine borrowed it and his buddies took turns throwing the knife into a tree. I was not amused. About ten years ago, I used the blade in a house demo project. No worries.
The knife just plain works, and works well. I have had it professionally sharpened but now I just use a cheap crock stick. The knife has seen a bunch of kitchen duty as well and it never complains. And yes, I have smacked the spine a few times to get through some pesky wood blocks. These days I do put some light oil on the knife after use. I have had it so long that I can't exactly remember what I paid for the thing. And yes, I was not too happy that it came sans a decent sheath!
Busse knives work well, feel good in the mit and while being quite costly, I think the warranty makes every penny worth it. These are just well built pieces of equipment that will work and work and keep working. Spend your hard earned dough and get something good. The investment is worth it in my estimation.
