The one with a bottle opener might not fit in a standard tactical sheath. I am tired of ordering knives without sheaths. I hope they have sheaths available when they are offered.
Based on the great work you do with the belt sander, you should make your own Kydex sheaths. It's relativiely inexpensive to get started and with some basic practice, you can bang out sheaths for your whole collection. This was my main reason for getting the tools to make sheaths, I was tired of not having sheaths for knives. It would have cost me hundreds of dollars to buy sheaths for all of my knives.
