Hi All -
I’ve been using “scary sharp” technique to sharpen my blades, but haven’t been very satisfied with it, so I recently bought a set of Norton combination stones (220/1000, 4000/8000, and a flattening stone). I’ve just begun using them, but I’m new to sharpening with waterstones, and am seeking your wisdom. I looked through the posts trying to find answers, and I apologize if this has been asked and answered many times, but I couldn’t find it. I have four questions:
1 – How long do you go between stone flattenings? I discovered that my new stones weren’t particularly flat out of the box, and went to town on them to get them that way, but I’m wondering how often I’m likely to need to take a layer off my stones to keep them reliably flat. I realize the answer to the question will have a lot to do with what condition the blades I sharpen are in before I start, but for reference purposes, assume I’m working with new 1” chisels that are rough ground, but never honed (RC60 hardness). How many would you expect to sharpen before needing to re-flatten the stones(and how long before I need to re-flatten the flattening stone)?
2 – I like to have sharpening sessions and sharpen several tools at once (this may be a mistake, but it seems more efficient). What do you do to avoid grit contamination? Do you keep each stone in its own bath while sharpening? Dip the tool in a separate bath to rinse the slurry off to look at the edge, or just wipe it with a cloth? Do you clean the swarf off the stone between uses? If so, what do you use (I was thinking of an old toothbrush, but I don’t want to load the stones with plastic).
3 – Because I’m a rookie at this, I’ve been using a Veritas honing guide, but I’m wondering about the roller getting charged with grit and contaminating the stones (or just damaging the guide). If you use a guide, how do you keep it clean when shifting from one stone to another? What do you do to keep it clean between uses? (If the directions provided advice about this, I missed it, and I seem to have lost the directions at this point – grrr…)
4 – Finally, do you completely lap a blade through a series of grits before honing the bevel, or can one lap and hone at each grit in turn, so as to avoid moving back and forth through the grits more often (which I suspect will require more rinsing and cleaning to avoid contamination).
Thanks in advance for any thoughts or advice you may have.
