I have two tactile favourites, one is an old sheep rib bookmaker's bone found in a box on the premises of a defunct bookbinding company in Clerkenwell, the other is a Lie Nielsen no. 212 cast bronze scraper plane.
But the tools I use most are a 12" Grobet half round cabinet makers rasp with a Python handle and an old gooseneck cabinet scraper.
For scraping bark off dogwood shoots and a variety of other small tasks nothing beats a suitably shaped chip of flint from the debris pile.
It's meant to be simple, not easy.
