Killgar,how is the steel on those stilettos, That is my favorite design,and most of those knives have bayonet type of grind that doesn't cut well.I am trying to find the ones with grind like the two you've modified!
As I recall, the steel was listed as 420, but of course you gotta take that with a grain of salt.
As I mentioned, the brand is Rite Edge, often listed as "Rite Edge folding stiletto", and they are sold by several vendors.
As far as my experience with the blades, first, they are hard. When I went to drill the holes for the thumbstuds I thought a brand new cobalt bit in my drill press would suffice, but it didn't make a dent. Only carbide would cut through, and it did very well.
The blades have a nice "spring" to them. By that I mean, if you bend the tip over (they're ground thin at the tip), it springs right back to straight with no kink.
It only took a short time on a hone for me to get the edges hair-popping sharp. I don't know how long that edge would last, I've been meaning to get some hemp rope and do some edge-retention tests just for my own curiosity, but I haven't gotten around to it.
Here's a little general info about these knives (I bought 5 of them)- For one thing, quality is hit and miss. What do you expect from a $7. knife. But I bought these with the intent to put some work into them, and I have a lot of experience, so I was willing to accept less than perfect quality out of the box. I bought five thinking that at least a few would be of suitable quality.
Here are some issues-
All kinds of blade play. The side-to-side can be fixed by tapping the pivot pin with a hammer on a hard surface, or replacing it with a screw assembly/pivot (this requires drilling the blade pivot hole a little larger, as well as the guard bolsters). A few had almost zero forward/back play, the ones that had more required custom fitting of the lock to the blade).
Fit and finish can be rough. They come with sharp points and edges on the guards. But that can be dealt with using small files or just sandpaper, depending on how detailed one wants to get.
Don't expect a perfectly centered blade. some are, some are close, and some blades rub the liner.
Three of my blades were straight, two were canted to the side, which I believe is warping from the heat treat.
Four of the knives I bought had blades that were straight with the handle from the side when fully open. One (pictured in my post earlier) had a blade that was noticeably canted forward when open. But I know a trick to fix that, which I used.
Now for the positive, and the reasons why I was willing to put the effort into them.
Solid handle construction. The liners are stainless steel (nor brass like a lot of stilettos). The bolsters, top and bottom, are SOLID stainless steel (not stamped and hollow like a lot of stilettos), and the bolsters, top and bottom, are SPOT WELDED to the liners. As I recall, the guard bolsters have 5 spot welds, and the lower bolsters have 4. So these handles are SOLID, and they make the knife feel very solid in the hand, unlike many stilettos I have handled that feel weak and flimsy like they will come apart at any moment.
Although there was blade play, the blades still lock up secure. I used a moderate amount of effort to try and force the locks to fail, but it didn't happen.
The springs are strong. In fact, in order to make one open easily one-handed I had to grind a bit off the spring to weaken it a little. But all 5 were easily opened with two hands. There wasn't a "nail-breaker" in the bunch.
None of the edges of the blades on all five knives would contact the spring when closed, not even when I let them slam shut. So the edges don't get dinged from contact when closed. Of course if you squeeze the knife hard when closed you can make the edge contact, but that's typical of this design of lock back. Adding a thumbstud creates a blade-stop, so in the case of my knives, it's impossible for the edge to contact anything when closed, ever.
The stock handles are on secure. Both pins and glue. But the glue is easily defeated with a little heat (heat gun, holding over a stove) if one want to remove and replace them.
That's about all I can think of at the moment. Feel free to ask me any questions. While this knife is not perfect out of the box, I think it's a great project knife, with lots of potential. And I think they are the perfect size, not too big, not too small like a toy. Like yourself, I'm a BIG fan of this type of knife, especially when the quality is good, or can be made good (or great

).
