Description: |
| The teeth on this saw-blade are separate blades which are clamped together with a pair of rods of semi-circular cross-section. The clever part is that the ends of the rods are fitted with notched sleeves that allow the pitch of the blades to be adjusted all at once. By adjusting them to an extreme, the blade ends together present an unbroken face that allows the teeth to be sharpened all at once. |
