I think a lot of the shorts or pants deciscion has to do with the work type and situation (aside from OSHA). In the posts above some really varied locations and such have been pointed out. There is a difference between a construction site or rehab, and standing in a shop or painting or attaching hardware to a cabinet. Also working alone or with a crew and lots of activity.
When I am doing site work especially outside , I want pants regardless of the heat, simply for the protective value. But assembling picture frames in the shop when it is 95 and humid ...... I will take my chances with shorts.
On the gloves with circular saws............... Holzhacker, how do you feel about the close fitting "mechanic style" such as those from Ironclad?
