I've been working with my hands for decades , framing , machinery you name it. Until recently.... I began building diy kit electric guitars. Hickory necks and sides , bass (Linden) wood laminate top and back. My hands react fiercely , from sanding , within two days almost useless. Is it just these woods ? Do I need kevlar gloves ? I now have a large blasting cabinet for sanding. Indeterminate this far. Thank You Jim
