With the Milwaukee, you hold a button and flick your wrist to open/ close it. makes it easy to use with one hand. any knives with a regular blade that do this? thanks

Bokker makes some knives like that, but I’ve always been partial to flippers like the CRKT M21. Does it need to have an actual button? That might limit your choices a bit.
CRKT knifes with flippers are excellent. The sound of the double lock variants are great fun.
