I most often use the chain saw of dropping drops, cutting the shoulder would allow the use of the frame saw, I think. I may try a replacement blade and make the frame.

The sharp saw will handle and 8x12 but not with out side effects. They work better on dry wood.

One thing I noticed with the sharp saw is the longer 26" blade with the 12 points not 8 or 9 will fold if you push it too hard. I used to complain they did not make a nice 26" with 8 tpi, I understand why now. The bodies are all the same thickness and can't handle the force applied to the longer blade, they are doing a lot of work. This is why the oriental version is pulled.

An off topic but related question I reasoned out, has to do with my Makita impact driver with the 3 amp hour battery, the larger one. They changed to 1.5 amp hour
batteries which are smaller and lighter. When the tool makes too many falls from great heights the lesser weight battery will not impact the handle and break it. I wonder if the engineers at Makita came up with this solution to save the driver body from breaking. I am using my smaller batteries now and am testing my theory. I like to think of my impact driver as a freedom tool, freedom from those lousy cords.
