I don't do very well remembering to transfer my knives from jacket to jacket (light jacket, work jacket, heavy jacket, winter coat) So I just have a knife or knives for each one. If I don't do it that way I walk out of the house with nothing but a a tiny keychain knife (and a gun, but still...)
I have a dress jacket that I wear to work on chilly days and I didn't have a knife for it. I was at Walmart and they had the CRKT M16 01s for around 16 bucks.
I once bought a Tac-Force 803 a long time ago based on this YouTube review, saying it was a good deal, (It wasn't a good deal):
The reviewer was completely wrong. After 4 minutes of me practicing (playing) with it, the thing loosened up so much it was ready to fall apart. Then a few days later the spring snapped.
Well anyway... even though the quality was crappy, I liked the ergonomics of the blade and it was a knockoff of the CRKT M16.
So I saw a real CRKT M16 at Walmart for 16 bucks, I thought it was a good deal so I picked one up to throw in my dress jacket. I like the knife so far. The knock off wasn't quite half the price but the real thing is easily 10 times better quality-wise.
