Budget skinning knife with replaceable blade?

I need a skinning knife to keep in my hunting pack. The kind I want has replaceable blades - like razor blade sharpness. Do any of our budget dealers offer a cheapie but goodie?

I’m thinking something like the Havalon line, or the Gerber Vital. But more budget…

I don't know if this would help, but I suggest going to fabricators or metal machining services like this metal machining services, for example. On my given example, the closest to knives, out of their products, are machine tools. A plus is they don't have any visuals of their product, so you could expect that they are open for customization of a particular product of your choice.
