Sanrenmu (or just "SRM") is a Chinese manufacturer which is well regarded among knife enthusiasts. So much so that it can be hard to find their products at times. Almost all of their products are in the $10 range and compare well to knives costing 5-10 times as much. Sanrenmu is rumored to make products for American manufacturers such as Spyderco.
Price: About $10
The B787 is another interesting EDC folder, presumably of SRM's own design. It features a back lock and anodized titanium liner with titanium scales. I do not know if it's actually titanium or not.
It was clearly designed to be ergonomic, and has one of the strangest blades I've seen on a pocket knife.
My review sample was purchased from exduct.com and took a little more than 3 weeks to arrive at my door from Hong Kong. I noticed there's a seller now on Amazon.
Blade length: 65 mm

With a clip and features with a beer bottle opening
While a bit strange, this looks like a great design. The back lock is as thick as I've seen on a pocket knife- it's thicker than the blade! It has jimping at the 4 main contact points with your hand as well as on the back of the blade for your thumb. The only weak part of the design I can tell so far is the lack of a well-defined finger choil, but it's not that big of a deal.
The clip is setup for right-handed tip-down carry and can't be moved. And just like the 763, the exposed part of the blade when closed is a bottle opener.
Wow, this is the strangest looking blade I have ever seen. It's actually a chisel grind, meaning there's only an edge on one side. But the tip is also chiseled as well. Also, the opposite side of the edge has about a one inch "swedge" in it, probably just to make it look cool. I guess you could call it some sort of "Razel" blade, meaning a cross between a razor and a chisel, but I'm not sure that's an accurate description either. Whatever it is, it's different.
There's also a finger hole for one-handed opening. It can be opened one handed, though I wouldn't call it ideal. I don't recommend closing it one-handed though, as the lock is accessed way in the back.
The chisled tip is hard to explain. My theory was that it's either there to make the knife looks less threatening or as an aid to open packages and such. Again, it almost looks like their own attempt at a razel shape.
I originally thought that the liner and scales were both aluminum, but exduct.com claims they are titanium. I'm not sure I'm smart enough to tell the difference, but the knife has a ridiculously solid feel to it, so I can believe it. My only skepticism is that I'm getting Ti for that price, though I have read that Ti is fairly plentiful in China, so I'm leaning towards believing it.
The interior liner is anodized blue, but one side of it looks purplish. I have no idea if this is intentional or a by-product of some heat treatment, but it looks kinda neat either way.
The clip only has one location on the handle. Not a deal breaker for me, but then again, I'm not big on clips. It is deep carry though. There is also a lanyard hole / glass breaker at the end of the handle, which is blue on one side and purple on the other.
There are what appear to be metric hex screws holding the knife together.
Fit and Finish
Overall good. I would've rated it as excellent, but there's a little bit of a gritty feel where the blade starts to open, which makes it a little harder to open one handed and doesn't feel that great. My guess is that it is going to smooth out on its own over time. If it gets too annoying then I'll probably just disassemble and sand the offending surface.
But other than that, there's no scratches, tool / machine marks or flaws in the anodizing that I can see. It has the same high quality stainless steel clip that my other SRMs have. The precision machining is pretty much perfect on this sample. All of these SRM knives look much more expensive than they are.
This knife uses a very beefy-looking back lock mechanism, which I tend to prefer over liner-lock knives. The lock is a serious piece of steel, and if it looks half as well as it looks (no issues so far), then I expect this knife to have a lockup that's on par with some of my more expensive knives.
I'm super impressed by the back lock on this knife. Lots of people see SRM as nothing more than a oem / cloner / counterfeiter, and this design shows that they deserve their place as a manufacturer in their own right.
When I bought this knife, I wasn't sure if the design was made to be functional, or whether this would be an odd decoration in my knife drawer. But after carrying it EDC (which I do for all my reviews) for a week, I can say that this is a functional design.
Again, I wish it had a more defined finger choil because my index finger seems to want to creep toward something that's just not there. I've gotten used to feeling for the jimping and stopping my finger there. But that's just a minor gripe.
The chiseled tip does indeed work great for opening mail and packages. I haven't used to to pry anything, but would probably do OK as long as you remember it's not actually a pry bar.
This is a cool knife. Love it or hate it, it's certainly innovative. Overall this is a great knife - better than I thought it would be. Since I tend to EDC light, this knife is just a little heavy for me to EDC. Others will probably find it about perfect, though, especially since this knife is solid metal. I still may take it with me into the world where its non-threatening looks would be helpful. But for the most part, I think this is going into my toolbox.
So, in conclusion, for me, this is perfect for my toolbox. I think this knife is going to be better suited for cutting drywall than it would be in the woods, though again, for most people this would be a fine EDC choice, especially if you like something different.
