I have rheumatoid arthritis in my hands and metal and plastic weaving needles slip out of my fingers. The flat surface of the wooden needles make them much easier to hold. The smooth edges keep the yarn from snagging and are gentle on my often sore fingers. The only thing I would change is to make the tip slightly thinner.
Weaving needle is smooth with no splinters. Very carefully hand crafted. Easy to use on my smaller looms and rigid heddle looms for details.
Terrific. Just love it.
