I agree with Barb that having the word 'pyrography' as a tag in most items might not be best. I understand that that is what the technique is called, but how many buyers are going to know that and search by that term? As a novice to woodworking, I definitely wouldn't search by that word myself. Maybe leave it in some items and if you're getting lots of search hits, add more. If you don't get search hits...don't use it.
I looked at some of your items tags' and they could use a little work. Some have spelling errors (e.g. in this item below). "weddign ring box" "jeweler box" instead of jewelry

You don't have to have 'box' as a tag if you already have 'jewelry box' or 'wedding ring box'., etc. A tag of 'jewelry box' is relevant for searches of 'jewelry' 'box' or 'jewelry box'. Go through and delete tags that are already part of other tags -- that way you can include more varied tags to get more views!
