First off lets get this photo sorted out so we can see it.
Isn't that better ?
Second blade locks are HIGHLY OVER RATED.
It's a fun thing to have on the knife and to play with and fidget with.
In use I have never found I really NEEDED a blade lock.
I have just scads of similar knives (I'm a Case Trapper junkie) and I've never had the blade even hint at closing on me, but, knock on wood, I know how to use a slip joint knife; been doing it for fifty some years so . . .
Third the bone scales on these slip joints are beautiful / handsome, they have decent grip and traction in use, they aren't as cold to handle in cold weather as say an all Titanium frame lock would be.
They are inexpensive enough one can buy another one now and then as a treat without feeling guilty and as you said there are so dang many of them there is a lot of variety to please everyone.
I just got a Case Trapper with Black Water Buffalo scales and I'm quite happy to have it and have carried it for weeks . . . even though I have about forty cajillon other Trappers of various handle variety.
PS : and these blade shapes, in many ways, are superior in USE to the overly thick, overly wide "high tech" modern locking knives.
That said
I'm also enjoying my new locking folder in Maxamet.
As Richard Alpert once said : you got to play at all levels.
Need a knife to match your Christmas Pendleton Wool Shirt ?
No problem with Case . . . they got a knife for every occasion !
