These are amazingly well made knives. 2.25 inch blades and 4.75 opened with droppoint blades made out of swedish 12C27 stainless steel, slightly hollow ground. I would not consider them primary knives, but they are the perfect size for your keychain or when opening your primary EDC folder to open a box might scare people around you. The backsprings are strong and so far I cannot make out any bladeplay. Photos show a Vic Classic and a Sanrenmu 710 for comparison. The WA611-A1 can be had for around 10 dollars including shipping and gets cheaper if you take some more for your friends or family. Good stuff.
