Having now found a pile of photos from the earliest stages of this venture, I want to take a little step back in time to pick up on something a bit fundamental - grinding bevels. There’s piles of good info available on different bevel types, their purpose, pros and cons etc. It seems to me that there’s a lot of good, rational reasons as to why some bevel profiles are better for some purposes, poorer for others and so on. It also seems that there’s a high degree of subjectivity and personal preference - perhaps any sensible profile, well sharpened, is capable of cutting stuff so, the question is really about best matching blade / bevel profile, size, blade thickness, blade steel to your intended purpose.
So, for now, this is what I’m looking at as a basic bevel:
This is a compound, or double, bevel meaning that the blade angle changes twice on each side going from the flat to the primary bevel to the secondary bevel. The secondary (or micro) bevel provides the cutting edge.
This grind profile might be called ‘Scandinavian’ or ‘Sabre’ depending on how close to the spine the primary bevel reaches. It is not a ‘Zero’ as it has a secondary bevel; for example a ‘Scandi-Zero’ grind would continue the primary bevel in to the cutting edge.
