The Kitchen Knives ID Difference

Kitchen Knives ID is a Magetan-based knife platform founded by Omar - a knife maker who works alongside local blacksmiths and craftsmen in East Java to produce handmade knives using traditional forging techniques. The platform also supports and showcases other experienced Indonesian knife makers, making each knife a genuine product of local craft tradition. SanMai construction sandwiches a hard leaf spring carbon steel core between layers of soft iron cladding - combining a hard, keen edge with a tough, flexible body. The kurouchi acid-etched finish creates a striking contrast between the dark cladding and the polished edge bevel. The petty is the Japanese utility knife - nimble and precise, ideal for peeling, trimming, and detail work where a larger knife would be unwieldy. At 150mm, this is a versatile length suited to both in-hand and board work. The amboyna burl and rosewood handle is warm, grippy, and visually striking - each piece unique due to the natural figuring of the burl.

Care and Maintenance

• Hand wash only - never dishwasher
• Dry immediately after use - carbon steel core will rust if left wet
• Apply a light coat of food-safe oil if storing for extended periods
• Expect a natural patina to develop with use - this is normal and protective
• Do not cut frozen food or bones - the edge will chip
• Sharpen with a whetstone to maintain the edge
• Store in the included saya when not in use
