I have some of his knives.
The only disappointing experience was with a Small Sebenza about 12 years ago that simply would not hold an edge--almost as if it had evaded heat treating. I sent it back to have it refurbished and re-bladed and it worked fine after that.
(Well, actually, the next disappointing experience was the loss of another Small Sebenza while hunting elk on horseback some miles south of Jackson Hole--but that was no fault of the knife or its maker! By the way, if any of you find one out there, it is in one of the now-defunct nylon belt pouches and I trust you will return it to me?!?)
Since I returned the one knife to them for a re-do, they have used two different steels and I believe they now use S30V for the Sebenza.
The Sebenza design looks to be bullet proof. I have not heard of any being tested to failure, but the inherent strength of the liner lock is appealing to me.
By the way, I talked to Mrs. Reeve at the Blade show because I heard they had discontinued production of the single piece fixed blade knives. She explained that their blanks had been made by a long time friend of Chris's in South Africa. When that friend decided to retire, Chris found himself at a crossroad--find another maker of the blanks, or concentrate on other types of knives. He decided to concentrate on other types of knives.
Therefore, if you like the one-piece fixed-blade Reeve, you better buy them now, and it will probably have to be on the secondary market. I understand that they kept enough blanks on hand to meet whatever backorders they had at the time they stopped taking orders for these knives and to be able to honor the warranty on any knives that came back to them.
Hope this is useful,
Larry
