I don't think it's cerakote, for several reasons. First and foremost, you can see lots of posts where people chemically strip the coating off Busse knives. According to google searches, Cerakote does not respond to chemical stripping. Secondly, Cerakote is highly regarded, and I think if the companies were using it, they would say so.
I believe it is a powdercoat, which is available in a textured formulation (a.k.a. hammertone/wrinkle/crinkle). It is probably an epoxy powdercoat.

"Black Traction Coating is the proprietary name of the finish TOPS Knives uses on its blades through the services of James Bowen. We use an
epoxy hybrid base with polyester in it, company President Mike Fuller said. It is electrostatically applied in its
dry powder form, and it goes on the blade between three and five thousandths-inch thickness. The knives are then put into an oven and baked at a little over 400 degrees Fahrenheit for about 17 minutes, depending on the thickness of the material. Its not an ultra-smooth finish like some coatings have, and it enables the user to hold the blade for close work if necessary.
