Overview

The DIYSELF 30 is a knife listed under DIYSELF's tool range, model number 30, though the seller has not published blade material, length or lock type for this listing.

With no attribute data or description supplied, there isn't enough here to characterize blade type, size or handling beyond what the title states. Buyers who already know DIYSELF's model 30 by name or photo can compare price, but anyone shopping on specs alone will need to look elsewhere for confirmation.
