These thumb and finger guards are the best insurance against cuts on the thumb and fingers from carving with hand tools. They fit well, are very comfortable, and are made of top quality leather.
I left a review on the small finger guards as well. The fit on these is perfect, and I like how the leather wraps around and over my thumb tips. They feel secure and comfortable without compromising my dexterity like a full glove does. For reference: my thumbs are ~5.5cm from base to tip and I have slender fingers.
Fits me perfectly and stays on my thumb.
