These contact wheels are an excellent addition to any grinding arsenal, with the quick change spigot it's easy to switch between a flat platen, and your contact wheels as they use the same tooling arm!
The smaller 5" wheel is a perfect size for aggressive hollow grinds on daggers straight razors, while still being a great size for other grinding applications, such as tearing off a layer of thick forge scale or grinding the profile into an ax.
