Silky Saws: maximum cuts + should you sharpen them?

A few tips to help you get the most out of your Japanese saws

These tips are important because, unlike North American saws that cut on the push stroke, Japanese saws cut on the pull stroke. A different sawing motion is required and you should know that the blades can be snapped through incorrect use.

1. Cut on the pull stroke, glide back on the push stroke. Cutting when pulling uses less energy, gives the user more control, and results in a straighter cut. 
2. Use a smooth, gentle sawing action; its not about applying maximum force or how strong you are.
3. Do not twist or bend the blade while sawing and ensure the weight of the branch does not pinch or catch the blade - or you may snap the end off the blade.*
4. Use the right length of blade for the job:  general rule of thumb is to cut branches with a diameter equal to no more than 1/3 the length of the blade.*

To sharpen or not to sharpen?

Most Silky and ARS saws have impulse-hardened blades. This process creates a very sharp blade that lasts 3 times as long as a conventional blade but it is very hard to sharpen without removing the extra hardness from the steel.

For that reason, full-grind sharpening is not recommended; if you must, just do a light touch-up with a file. Replacement blades are available once the blades are really dull.
