Research is necessary part of the advancement. Heading forward is one of the main goals of TK Knives. We always try new things, investigate the old ones and strive for improvement. Stonewash is known world-wide. Tungsten wash was for the first time implemented by TK Knives. Tumbling of the knife is done in Tungsten carbides, previosly soaked in a strong salt. According to our judgement Tungsten wash is subtler way of surface finishing, which does not damage the edge and geometry of the knife like stonewash and does not lose on appeareance, rather emcores it.
