[Wait. No. This isn't a good idea]

...this may be too much for a complete beginner. [Dojima takes away the electric round saw and instead gives a traditional saw, with no electric components at all]

Try to use that. You'll need to apply some force but it should be a bit easier to control...I think.

[Here, have a plank. Dojima traces a relatively straight line from end to end and holds the wood down]

Give it a try. Be careful with your fingers.
