Update
Second review and it’s now 5* not 4. I’ve used this knife at work as a firefighter and it has held up brilliantly. That D2 is amazing. As it’s not an expensive knife you’re not afraid to use it and it’s small enough not to be threatening. I started to get a good amount of blade play so I opened it up and for some reason the nylon washers were all chewed up. I went on Amazon and bought some brass washers (M4 I think) and it’s worked perfectly. I’ll be getting their other D2 models now.
