When you manipulate weed and stuff you can easily get hurt by thorns. Is there a type of garden gloves to avoid and a type to favor for reliable protection?
If you can handle some loss of dexterity, leather welding gloves are surprisingly affordable for a long, heavy glove. The problem with "good dexterity" (thinner, tight) gloves is that serious thorns go through them (through they will protect against some of the smaller ones.)
For a lot of the nastier stuff I cut into small-ish parts with long handled pruners, and use the pruners as tweezers, rather than trying to handle it at all directly.
