For a chef that deserves the best kitchen knife set.
The finished blade is Black Chromium non stick honed "Cutting Class" martensitic steel with the handle in forged and machined stainless steel. The weight is magnetically attached and maybe removed for an alternative weight or indeed slid back or forward to re-balance the chef knife.
You can order a standard kitchen knife set with recommended weights or may order light or heavy knife set as you prefer.
I use my knives in many ways. The sliding balance means it has a perfect balance all the time.
the standard set includes
Utility chef knife and 30gms weight
Santoku chef knife and 40gms weight
Petty chef knife and 20 gms weight
