Allday Goods combine professional-grade blades with handles fashioned from 100% waste plastic, making beautiful, sustainable tools to be used every day.

These Santokus are the Japanese equivalent of the Western chef's knife. Translated as "three benefits," the Santoku is perfectly suited for slicing, dicing and mincing; the vast majority of knife work required in any kitchen. Their length is accessible enough for the most inexperienced of cooks, whilst that subtle rocker (curve) on their edge allows the professional chef to work more quickly.

The blades are hand-forged by Goto in Seki, Japan, a region known globally for its history and experience in producing fine kitchen knives. They're fashioned from incredibly hard (65 HRC) SK4 carbon steel, which keeps a razor-sharp edge, but should be cared for appropriately to ensure they work to their full potential. Instructions on how to look after them are included in the box.

The magic though, is in the handling. Waste plastic is collected, washed, shredded, melted and formed into those ergonomic, octagonal handles. The waste source is always changing depending on what's collected, so there can be slight variations in colour. That means no two handles will ever be the same–every one is completely unique.

The knives come in attractive presentation boxes, each containing a "meet the maker" card, limited edition sticker, care instructions and a penny to ward off bad luck.
