This not-too-thrilling entry was inspired by reading that people were getting stung by nettles and scratched by brambles while clearing vegetation. I've found that thick, closely woven clothing gives some protection. As for gloves, a good compromise might be all leather, lined types. Those made with fairly thin, supple leather allow use of tools while providing some protection against thorns. Even with careful handling, thorns may go through the leather, but the lining should reduce the probability of injury. Puncture wounds could become infected by bacteria etc. present on the thorns, possibly a serious health risk. Heavier duty clothing and gloves are probably advisable for handling hawthorn/blackthorn and the like.
