A hand-held surgical cutting instrument for cutting bone material with a bone-cutting surgical blade shaped to fit the surgical cutting instrument, comprising: a hand-graspable body for manipulating the cutting instrument; a blade coupling mechanism attached to the body and being configured to attach to the bone-cutting surgical blade, the blade coupling mechanism comprising: a first coupling member including a first blade-contacting surface and a first outer perimeter sidewall adjacent the first blade contacting surface; a second coupling member including a second blade-contacting surface facing the first blade-contacting surface of the first coupling member, the second coupling member including a second outer perimeter sidewall adjacent the second blade contacting surface, the second blade-contacting surface and the second outer perimeter sidewall meeting to define an outer edge, the second coupling member including a bore through the second blade contacting surface, the bore and the second blade contacting surface meeting to define an inner edge; and blade-engaging protrusions projecting from at least one of the first and second blade-contacting surfaces, the protrusions being spaced closer to the outer edge than the inner edge; characterised in that the first coupling member comprises a shank extending from and normal to the first blade-contacting surface, wherein the shank is slidably received and extends through the bore in the second blade-contacting surface, and the shank further includes a blade receiving recess. a hand-graspable body for manipulating the cutting instrument; a blade coupling mechanism attached to the body and being configured to attach to the bone-cutting surgical blade, the blade coupling mechanism comprising: a first coupling member including a first blade-contacting surface and a first outer perimeter sidewall adjacent the first blade contacting surface; a second coupling member including a second blade-contacting surface facing the first blade-contacting surface of the first coupling member, the second coupling member including a second outer perimeter sidewall adjacent the second blade contacting surface, the second blade-contacting surface and the second outer perimeter sidewall meeting to define an outer edge, the second coupling member including a bore through the second blade contacting surface, the bore and the second blade contacting surface meeting to define an inner edge; and blade-engaging protrusions projecting from at least one of the first and second blade-contacting surfaces, the protrusions being spaced closer to the outer edge than the inner edge; characterised in that the first coupling member comprises a shank extending from and normal to the first blade-contacting surface, wherein the shank is slidably received and extends through the bore in the second blade-contacting surface, and the shank further includes a blade receiving recess. a first coupling member including a first blade-contacting surface and a first outer perimeter sidewall adjacent the first blade contacting surface; a second coupling member including a second blade-contacting surface facing the first blade-contacting surface of the first coupling member, the second coupling member including a second outer perimeter sidewall adjacent the second blade contacting surface, the second blade-contacting surface and the second outer perimeter sidewall meeting to define an outer edge, the second coupling member including a bore through the second blade contacting surface, the bore and the second blade contacting surface meeting to define an inner edge; and blade-engaging protrusions projecting from at least one of the first and second blade-contacting surfaces, the protrusions being spaced closer to the outer edge than the inner edge; characterised in that the first coupling member comprises a shank extending from and normal to the first blade-contacting surface, wherein the shank is slidably received and extends through the bore in the second blade-contacting surface, and the shank further includes a blade receiving recess.
