These are made by No Lie Blades. Virtually indestructible. They have a felt edge that you soak with water and apply lipstick to. Lasts much longer than plastic and chalk marking trainers. You can check them out on NLB's website or @ Trainingknives.net. They sell as a kit for over 100.00. These knives came with a plastic sheath as well when I got them. (No longer available) Great for reality based training. "The mark doesn't lie!"
