I have seven Manixes. I really like Rex45. I really like that build. Do I need eight Manixes? Either way, awesome choices. These Rex45 Manixes make for killer knives.

Your price is very fair. The exact AD20.5 config you have is retailing for $250 most places. Amazon has it in s35vn for $179 and the SR1 lite for $50, so you’re still $40 under that (and I prefer 3V). Great price. 👊🏼

Prolly just design preference. Ive owned all of them and still have a PM3, Arcade, and an ad20.5. Dont like the scales on the Demko tho, pocket eaters, but im sure if I got some aluminum aftermarket scales on it Id like it a bit more
