Cheng Fei visits Japan every year to find good knife makers, importing their hand forged knifes to Australia. While good quality knives are durable, there is no knife that can hold sharpness forever without good maintenance. Cheng Fei sources and imports the best ultra fine Japanese natural whetstones from miners and vintage whetstone quarries in Kyoto Prefecture and sells them in Australia under Daodai knives & whetstones imports.
