Four inches is the long end of folding
A four inch blade in a folder gives you a fixed-blade length that still shuts. You can draw slices through a sausage or a rope without repositioning, and you get enough spine to press on with your off hand. The cost is that the closed knife is a full eight inches deep in your pocket and the lock is now carrying a lot more leverage. Do not baton with it. If you want a fixed blade for that work, start with our notes on how Damascus handles moisture first.
Bone, and why every one looks different
Bone takes polish but keeps its own grain, so the cream color runs light and dark across the scales and small dark flecks are part of the material. It hardens rather than softens with age. Extreme dryness can craze the surface over decades, which is why we tell owners not to store bone-handled knives near a radiator. Our page on storing knives properly covers the sensible options.
Opening it
The hole through the blade takes a thumb from either side. It is slower than a flipper and quieter, and there is nothing protruding to snag when you draw the knife out. Shut, every face of the knife is smooth, so it does not chew at the lining of a jacket. For a much smaller everyday alternative, the original Tsetse Fly folder is a two ounce knife.
Care: Carbon Damascus and bone both hate being left damp. After use dry the blade, then work the cloth into the gap between the scales and the liners where water collects. Oil the blade lightly each month. Never soak the knife and never put it in a dishwasher: the heat and detergent will dull the bone and strip the oil out of the pivot in one cycle.
FAQs
Does bone yellow? It warms slightly with handling. Most owners like the result. Sunlight speeds it up unevenly, so store it in a drawer.
How strong is the lock at this length? Strong enough for normal cutting. A four inch blade multiplies any sideways load, so cut, do not lever.
Is it legal to carry? That depends entirely on where you live. Check your own state before you carry a four inch folder.
Can the scales come off for cleaning? We would rather they did not. The pins are set at the bench, and refitting bone without cracking it is a workshop job. Send the knife back to us instead.

I was a little skeptical at first to say the least when looking for my next daily carry pocket knife. With so many companies promising quality over quantity but rarely delivering I had to do some research. After searching for a few days online I found Black Mamba Knives. I have to say I’m very impressed with the overall quality and feel of the knife. I ended up ordering a slightly less expensive model BMK-421 Rufous beaked Snake but can say without a doubt that it’s the nicest feeling knife I’ve bought. I probably have closer to fifty or more pocket knifes ranging from Kershaw to Buck and even some vintage Boker etc. This handmade knife from Black Mamba is worth every penny if not more. I now have a drawer full of Knives that I’ll probably rarely use. Thanks again for the awesome build and I can’t wait for the chef knife that I also ordered. This is my go to knife company from now on. If your contemplating on purchasing from this company verses another you need to give them a try.

It’s a really nice knife. I really like a nice bone handle. There Damascus work is really in depth. Great work. I gave it only 4 stars only because of the false advertisement. The ad description says the knife is 8” long. With a 4” blade. In fact the knife is about 6”3/4 long. The blade is only 3” lonv and the handle is 3-3/4 long. Not 8”. Then when you go into the knife description it says the knife is 7” long. So which is it. I’m a man with big hands. I’m looking for a nice long large knife. Maybe the custom knife I’m going to have done will be right

Ok, the knife is as advertised. The Damascus is pretty and overall it is well put together. Not a bad knife for $72, but it is not made in the USA. After researching many sites I found that the most likely country of origin is Pakistan. I spent 16 years in the military and was wounded in the Middle East. I try not to buy things from countries that aided the killings of Americans. My bad for not researching earlier. If you want a US made knife go to allamerican.org. It will lead you to many choices.
