We had to wear those Kevlar backed gloves /mitts in our logging company, long before the chain brakes came out in the mid late 1970s. At the time that was all the hand protecton we had from kickback. My brother won a safety award for wearing them during a kickback accident with his non chainbrake saw. The kevlar and glove was wrapped around his fingers so tight the foremen had to cut the glove off with a knife.
Then it got real strict when the company decided the fallers must wear the kevlar gloves with double palm leather also if we helped the skidder operator choke up.
Eventually years later with good chainbrake design , reduced radius bar noses the kevlar glove legislation was removed.
