One handgun I think everyone should have is a 4" .357 Magnum double action revolver, preferably stainless. You can practice/target shoot with .38 Special, defend your home with hotter loads, or carry and conceal it if you have to. It might be a stretch to say you can hunt with it, but it makes a pretty good trail gun. It is not ammo sensitive like a semi-auto, and you can get loads from mild to hot, as well as shot loads. It can serve well enough in a lot of roles, but often it is not the best choice for a specific role. If you own a lot of handguns, you may not use it much. But if you ever consider seriously thinning the herd, it might be one of the last to go. Point of all that? Many knowledgeable folks here say similar things about the BK7. In an interview, Ethan said his goal was a modern, better version of the iconic KA-BAR US Military knife. I think he did an admirable job. IMO, The 7 should be looked at in that light.
It is difficult to do much with detail work with the actual point of a trailing point knife. But they slice really well, and they probably stab pretty well. The 5 and 15 are often mentioned for martial arts and kitchen duty. Seems a weird pairing, but it makes sense. My bet is the people who like them do more slicing than chopping and heavy batoning.
The 16 and 17 can do a lot of the things you do with a knife. I like straight clips on small blades, in case I want to do a bit more with the point, but that's just me. The 11, 14, and 24 are really easy to carry. I personally would like to see a shallower profile with a bit more point, but again, that's just me.
If you just want a big azzed blade of "conventional" shape, 9. Want bigger and heavier? 20 or 29. The 3, 4, and 21 each seem to be pretty darn purpose built.
You can take just about every Becker in the lineup and figure out how well it will do certain things. Every now and then, someone "discovers" a "different" use. A good example of this is people commenting on how well the recurve of the 4 and 21 works as a draw knife. However, I wonder if it was a surprise to the designer?
The point of all this rambling is this. Ethan may have designed or built an "art" knife somewhere in his past. I cannot say. But virtually all the knifes in the current lineup are designed to fulfill a purpose, to DO a job. "Becker knives work for a living" isn't something some advertiser thought up. Well, OK, maybe it is, because I don't really know. But it is truth, no matter where it came from. Once you figure out what you want the knife to primarily be used for, and the more you understand how blade shape helps you do it, you will do a good job of picking out good ones. Maybe more than one, but good ones.
What really needs to happen here is someone should persuade Ethan to write a mini history on the design goals, intended purpose, etc. of every model. I have never met the man, but on video he gives very insightful, engaging talks about any model you care to discuss. It would be cool if all that was written down in one place.
I guess I got a little long winded and sort of hijacked the thread. Sorry. But having typed all that, I'm NOT going to delete it!
