I’ve started working on my first workbench (Paul sellers style)and got the top completed tonight. This has involved a lot of planing to true up the laminated dimensional lumber and my left hand in particular has taken a beating.

I’ve developed a couple of blisters from what I can only guess is the part of the front knob on my planes where the screw is. The surface there on my planes is smooth and/or the screw itself is a bit recessed so I don’t think it is acting as an abrasive. I’ve also tried to be very conscious of not forcing the plane too much.

There is is still a LOT to be done to complete my project and I would prefer not to keep getting blisters. Any tips? A glove for my left hand? What might I be doing wrong?
