I am just starting out and ordered a square gravers blank from GRS, I have been looking into the correct way to sharpen it so I can cut through the metal smoothly, the videos I've watched on it involve grs fixtures, crocker style fixtures or just sharpening by hand, I'm sure the grs would be the best for the job but its just a little pricey, i was wondering if theres a cheaper way for a beginner or whether i should just save up. Thank you for any help
