The ones I seem to reach for most are...
My Greco Companion - my "go to" knife... sometimes I treat it like my "go to hell" knife! I have cut stuff with that thing that has NO business being cut with a knife and it is still going strong! I have only sharpened it a few times and aside from the chips caused from absolute abuse, the A2 edge is razor sharp. Cost me a total of 50 bucks - I really can't complain!
My Rinaldi L.E.O. - my hunting companion, tree trimming knife, showoff custom blade, etc... It is simply a functional work of art! It locks into my hand like a natural attachment, cuts like there's no tomorrow, and is a damned nice looking knife to boot! It is my favorite fixed blade BAR NONE.
Busse Basic 9 - My BIG "go to" knife. It does all the big, brutal, nasty jobs that my Companion is too short to pull off. It has chopped wood, hacked brambles, demolished furniture and appliances (long story with lots of "me and my brother were sitting around drinking and..." content), opened cans at cookouts, whittled tent stakes, pried fenceposts loose, chopped concrete (how else was I supposed to get the fenceposts out?!), hammered MANY a nail in a pinch without a hammer in sight, and generally come to be the knife I would trust with ANY big job. It's a big, sharp whomper that I can utterly depend on.
As for folders - I used to depend totally on my Sere 2K. That has ended. The thumbstud broke off (under normal use) and I requested a new one. They told me "no problem, just send us your address and we'll send you a new thumbstud". Well, it has been more than a month and MANY, MANY replies later (including my mailing address in every single one) and since that email (stating they would send me a new thumbstud) I have had no response, and NO FREAKING THUMBSTUD from them. Soooo, I guess my advice is to buy and Al Mar knife, and it will work well, but if it breaks, you don't have a snowball's chance in hell of getting a replacement part. Even something as cheap and corny as a thumbstud that probably doesn't even cost a quarter to make. I guess you could say I'm in the market for a new folder. Anybody have any suggestions that would replace the Sere 2K?
