Sinclair Knives Australia is the practice of Mark Sinclair, a Western Australian maker and Australian Knifemakers Guild full member. The focus is the kitchen: chef's knives, gyutos, petty and fillet blades, alongside Damascus vegetable choppers, each ground and finished by hand. The maker's site carries a working gallery of current pieces, and Sinclair is a familiar name at the Perth Knife Show, where his kitchen knives regularly appear.
