The spyderco medium has been lapped, and is ready for use. This is a ridiculously hard stone. As hard or harder than barber's hones. It should give a lifetime of performance before ever needing to be lapped again. All it needs is a powdered cleaner and a scotch pad to wash the swarf away.
Model 302M $40 shipped CONUS, international will be additional depending on the country. Lapped.
No need to introduce the DMTs. They are pure lapping stones. X and XX.
Asking for $40 for the X-coarse. D8X
$55 for the XX - coarse. D8XX SOLD
