Ok! some basic info:
Going rates are usually between $65 for 180-240mm Sayas and $70 for 270mm saya's for most woods. Longer blades will be a bit more since I would need to order more wood. Shorter blades will be a little less, maybe around $55 or so. Sometimes I can get wood on sale or use less expensive woods if the customer needs to save money.
I prefer to have the knife in hand so I can fit the knife to the saya better. I have done them from tracings, but need to do them oversize to account for any dimensional variances from the drawing to the knife. I may try to do some generic saya's, like for a 210mm gyuto, 240mm gyuto, etc that will fit a range of knives that may be a bit looser.
Bocote, Lacewood, Bloodwood:
Cherry on top, Bolivian Rosewood on the bottom IIRC:
I like Bolivian Rosewood and the Bloodwood the best so far; nice figuring and take a nice finish. I have some curly maple, but the figure isn't really consistent through the pieces. Same with Lacewood; some has really nice, tight figure and other pieces are much less figure, more of a splotchy look. Walnut and cherry are fairly plain woods as well that will take a decent finish. I haven't used Bubinga yet, but I have several pieces here.
