Das zeichnet DMT Dia Sharp aus
The Dia Sharp line uses monocrystalline diamond bonded to a steel plate, offering faster cutting and longer life than conventional abrasive stones. The extra-fine grit is optimised for honing and polishing rather than aggressive reshaping, making it ideal for maintaining an already sharp edge.
Ideal for...
Outdoor enthusiasts, chefs, and tradespeople who need a reliable touch-up solution in the field or workshop. The compact size suits knife rolls, camping kits, and professional tool bags where space is limited.
