Snap-onTOOLS PK150 - (Utk150)

It’s not because it’s Snap-On, but it sure fits. I’ve had another of this model for 3-4 years at work, left it in my pocket and brought home. Reminded me to get another. It’s like a semi-auto pistol, load 5-6 blades and you simply push top button to pull dull blade out ( or flip over), pull lever & wallah! New blade ready to go. You don’t have to open anything or take anything apart. Literally 5 in the clip, 1 in the chamber! A genius idea and Snap-On obviously a big plus, quality you can feel!
