That cheap hardware store stuff gets me every time too.

@fionat55 yeah Jerry's right about that. I swapped to a 2mm chisel last year and never looked back. The heat transfer is just so much more consistent with flat tips on big ground planes.

Same thing happened to me last year @mason.drew. Was using the actual expense method for years and an accountant friend looked at my return and said I was leaving money on the table. Switched to the standard mileage rate and my deduction jumped by almost 40 percent. Had no idea I could claim parking and tolls on top of the standard rate either. Made a huge difference for my bottom line.
