One of my favourite tools is my Japanese Shinto rasp. It is a precision piece of kit and it is one of the best rasps I have ever had but it is some times just a little too big, and other times a lot too big. This little tool make it into the spaces where the bigger rasp will not go. It could be thought of as a manual dado blade.

Step 1: Get Some Cheap Blades

I bought a pack of a dozen hack saw blades from a two dollar store. For this one I snapped three of them in half to give me 6 blades 150 mm long.

<p>I could have used this idea yesterday! Good idea. I bet you could stack up jig saw blades in a similar matter for use on holes to shape.</p>
<p>Good idea.</p><p>At the stage that the blades are spaced apart, clamped together and glued, why not put two holes through and bolt together . It would be stronger than glue alone I'd have thought. I can imagine that from time to time the bolt would get in the way, in which case you could just take them out (it would all still be glued so you're no worse off). Also those bolts could be used to attach a handle. </p><p>If the bolts don't fit the use, then a second suggestion would be to glue a piece of wood with the same width as the saw on the opposite side to the teeth, this would add strength and could be used as a handle</p>
<p>At the moment the glue seems plenty strong enough, particularly because of the large surface area. Also because these are cheap blades they are quite brittle and might snap if drilled. Using bolts through the existing holes on the full length blades is a great way to keep them alligned while gluing.</p><p>A handle might be a good idea if using it for any length of time but for the moment it is small to get into tight spaces and do small jobs. This means I use it fairly often but not for very long. To do big jobs I use my big rasps.</p>
