Arkansas Stones are all slow, being a time severed Carpenter Joiner all my life now aged 64, you can only imagine how many chisels and planes I have sharpened, my love for natural stones is zero, when I started honing chisels almost 50 years ago, an Indian oil stone was a given most of us used them, given the choice of synthetics we have today I would throw that Indian stone in the bin. PS I also hone razors professionally.
