MNTMU3: MU-3 Picker 1
Mantis Knives

This knife has been designed and re-designed countless times. Mantis wanted to be certain that; when stepping into the dive knife arena, we included everything that was truly necessary in a SCUBA tool. Serrated on one side, smooth edged on the other, blunted tip for prying and for secondary use as a flat head screw driver. The most innovative feature though, the eject mechanism on the sheath. Depress the sides and the knife fires into the users hand for a very quick draw.

Update... Sheath
Right after submitting this review I emailed Mantis again, and this time their customer service was extremely quick. I received a replacement sheath in the mail today. I'm extremely satisfied and happy to be able to continue carrying my favorite EDC knife. I still have no idea how the sheath cracked in the first place, but I'll try to pay closer attention to the replacement.

Pros: Blade Sharpness, Materials, Weight, Finish
Cons: Sheath/Scabbard, None
Purchased this about 6 months ago & loved it for EDC. Wore it every day & used it quite a bit as a utility blade. Haven't used it yet for personal protection. It's a little bulky but I got used to it, as long as I wore a loose fitting shirt. About 2 months ago I noticed a crack in the sheath. I did attempt to make contact with Mantis customer service, but they never answered my email. I finally wrapped the sheath with electrical tape, so I could continue to carry it. I give the knife a 4, but the sheath gets a 2.

Daily Favorite
Received this about 3 months ago & it's been around my neck almost every day. The few times I haven't worn it, had to do with me wearing a more fitted shirt. The piece tends to be slightly bulky but with a loose shirt it's good. It can be deployed easily with either hand, and I can replace it without looking or in the dark with no problem. I've used it on a daily basis for small tasks but not yet for self defense. I like knowing it's there if that ever becomes an issue. I would definitely recommend this piece.
