    Great little knife
    This is a small knife that fits in my medium size hands as if it was made for me! I am not sure what the scales (handle) are made of but the material is solid. It is a lock-back knife and it does lock firmly.
    There is zero movement of the blade when the blade is locked open. I can grip the blade with only three fingers and my thumb, but due to the design, the grip feels secure and that I will not slip.
    The of 8Cr14Mov stainless steel sharpens easily. I use a ceramic rod and a strop to keep these little knives paper shredding sharp.
    The clip cannot be moved from its location. This is a tip down knife. I do not use the clip but have not removed it because it does not get in the way.
    The knife has thumb studs that can be use but they a bit awkward to use. But if you are in a siaution where you have to open the knife one handed, they definitely work. just do not expect to flip them open.
    I ordered a few silver versions prior to this last order of 4 knives in black. The silver version is discontinued. I bought a couple of silver versions from FastTech for a small amount more. Now, even FastTech is out of the silver version.
    These are great for EDC knives for light duty (office, home). For heavy cutting, you will need a longer handled knife. Even if you are more of a heavy duty user, this is small enough to carry in your pocket while taking very little space.
    Buy a few of these and put them in your man bags, desk, pants pocket, kits. They are quality and usefulness way above their cost.
    Not an actual con but they no longer make the silver version for some reason.

    Surprisingly good and affordable knife
    - Affordable.
    - Excellent construction and details
    - Compact, easy to carry around as a edc knife.

    Read a lot of good stuff about Sanrenmu knife so I decided to give a try on this. It's a small knife, very easy to carry around and although is lightweight its construction feels sturdy and with good craftmanship. It came with a decently sharped edge but it can be better. It can opened easy with one hand however closing it can be a little tricky because of the locking mechanism position. Overall a great pocket foldable knife.
    - None at this price point.

    GREAT small knife with a super strong lock back.
    Exceptionally lightweight.
    Blade is small but does a very good job!!
    You really don't realize it's even in your pocket due to size and weight and it's there when you need it!
    My new EDC knife hands down for when at work.
    Left or right thumb stud opening.
    One right handed position for pocket clip only. No option for left handed.
