Twilight,
I'm not a blacksmith, but I work a lot with hammers, striking tools, and heat (gas welding torch).
I like the simple brown cotton gloves with the finger tips removed. These are comfortable, provide a good grip, soak up a lot of sweat, protect the main parts of my hand, and allow great finger dexterity and feel. These gloves are at their best during the cool season when the garage is a nippy 40 - 59 degrees. These gloves are available almost everywhere and are cheap. I buy them in 10 packs and go thru them pretty fast.
I also have a pair of the long thick leather welding gloves that extend well above my wrist. These provide more protection from heat and sparks, but they don't provide much feel or dexterity. These gloves are at their best whenever the torch is in use.
And last, I have a hybrid pair of gloves made of thin leather and a stretchy fabric; the fingers, thumb and palm are covered in leather with padding in key places. The back of the glove is made of stretchy fabric. These gloves come without finger or thumb tips. These gloves afford more protection than the brown cotton gloves yet offer the same finger feel and dexterity. They are also very comfortable to work in for extended periods. I have found that these gloves require a little maintenance to keep them soft a subtle. I air dry them overnight after every use. And, about twice a year I apply glove oil and mink oil to the leather and let them sit in the sun for a few hours; this keeps the leather soft and flexible and make for a very snug but comfortable fit. I found these gloves at both HF & Lowes and the cost was about $10, well worth it too. Lastly, these gloves have an excellent grip and feel on wood handles. They're almost perfect...
