I LOVE the knife blade. I used this to cut out leather luggage tags. I then embossed them with the regular blade after wetting the leather so the embossing stood out. I also added some HTV. They were a hit with my colleagues. For those who have this a bad review, your design cannot be too intricate. I used thick 7oz leather and it cut like a dream!  It takes a few passes to cut all the way through but my tags were PERFECT and I made 12 with the same blade without any issues.
