TheGent,
I have some experience on them. I had a Böker Plus Cattlemans knife, some kind of stockman knife. But it was a terrible thing. There was a lot of blade wobbling and pretty dull ootb. The next thing was the nailbreaking spring. Compared to the bladewobbling it was a little strange, but it was like this. I sent it back to Böker for replacement and they told me, that the knife is no longer made. So I got the money back. Not good thing end experience on this one.
The next thing I got, was a Rangebuster, some kind of a (back)locking Soddie. That´s a cool knife. No bladeplay and the lock is nice. The yellow handles seem to be a little cheap, but for the prize, it´s ok. I sometimes use it as working knife.
Comparing both knives - it´s a hit-or-miss-game. They were very prizey and for the prize as far ok. But the cattlemans knife had some bad issues. The yellow Rangebuster is a nice little knife.
Both knives were stamped "Made in China" and a 440-Steel is used.
Hope this helped a little.
