The Russlock is an interesting hybrid. It is a slipjoint, with a locking liner and a "purported" one hand opening device.
I say "purported" because on both that I own, they are to stiff to thumb open, like you do a straight razor. I need 2 hands to open, can close with one hand though.
For a pocket knife, it is quite slim, but a little heavy. The thumb "lever" can give you a poke every now and then.
I like the original blade, there is a graceful sweep to it. There is a Russlock in the Midnight Tested XX series with a drop point. Just does not look right to me after the original.
It only come in Tru-Sharp, the Case SS. There are many threads on the inferiority of Case SS, have a look through.
In my opinion, the Russlock will suffice as a pocket knife that does not get too much hard use.
And I just love the Case bone scales.
