Hi Joe
You wrote: "mid-tech/semi-custom/high end factory"
As one of the leading dealers in the world of tactical knives. I can tell you with some authority...you are very confused.
Perhaps I am. Were you referring again to Randall's? Do they even make folders?
As what you wrote has nothing to do with custom tactical knives. Randall lead the way until the mid to late 70's then the custom guys, many who made copies of Randall's stepped up and took the knives to the next level.
While I was attending Northern Warfare School (The Army sent me to Alaska in November on an all expense paid vacation...first night I spent the knife in a condemned building...Only the best for the Officers

)
During my two weeks there, one of the things we did was try to make a shelter...main word being tried. Part of the exercise was to cut out a piece of ice for a window in the shelter. A fellow Captain from the 82nd Airborne was sporting his Randall 14...and boy was he proud of that knife. He took it out and started chipping at the ice about 12 x 12 when he went to lift the ice up, the knife tip broke. Oh, I forgot to mention it was -25.
Of course I had to laugh and he quickly replied "Oh yea lets see what your knife can do". I cut out a 24" x 24" piece, put my knife under it and jumped on my knife. The ice lifted up with no damage to my knife. I lifted up his block of ice, dug out the broken tip. He was in disbelief, he kept say my Randall 14. I corrected him and told him he had a Randall 15. He asked me what the difference was...I smiled an put the broken tip in his glove and said "About this much".
He asked to see my knife and then asked me why it didn't break. I explained to him that the steel was cryogenically treated, meaning it was dipped in liquid nitrogen at around -162. Consequently -30 would have no effect on my knife.
He asked who made it and I said "Walter Brend". I explained that the cost about double what his did. He said he didn't care. Some sales are so easy!
