Small Keychain Knife, Mini Folding Pocket Knives with 10pcs Replaceable Surgical Blades, Scalpels Utility Cute EDC Box Cutter for Women and Men

The build quality is excellent. Edges are all comfortably-rounded. Just be aware that there is no backstop when opening the blade; see photo. Also, won't work with #15 blades without filing down the crossbar, which have a deeper belly than #11; took me a solid 5 minutes with a round Swiss file.

I really like the key chain clip ons that come with the surgical blade. What I don’t like is none of them secure to my pants belt loop as I like, They do have a tendency to feel like they’re attached…and they’re not! I did find a key clip on the I like and is extremely secure (Ahiller) but it had no surgical blade. This little knife fits the bill nicely. Very, very small but big enough to be used as a useful tool

The build quality is great, great size it comes with replacement blades and is very sharp. The two issues I had were that it doesn't lock closed and so it is easy to open, but it also opened up twice by accident. The final straw was the screws came out and it fell apart. I would recommend this if you are note keeping it in your pocket.

Perfect to keep on the keychain for any need

Bought 2 of these, first one the day I got it fell apart. The back screws were not secure and I get decently active at work, the screws fell out and I had an exposed razor on my hip for idk how long. I was able to secure it with tape until I got home. The 2nd one was a replacement, just put on some Thread-Lock and it works like a charm without falling apart. Other than that the blade and replacements are very sharp as expected. Being a slip-joint blade it's advised you use caution as it lacks a true locking mechanism. But overall works great for needing a convenient blade that fits on your keys, also it weighs almost nothing.
