Well that was a glowing endorsement *L* Thanks Tom!
For those of us who actually spend a good deal of time using straight edged tools having to re-establish the primary bevel is quite common. Chips, dings and even having a secondary bevel creep too far up the blade all necessitate re-establishing the primary bevel then finishing up with a new secondary edge. Type of wood, pairing or using a mallet, metallurgical makeup of the tool itself, all impact just how quickly the need for a new edge happens. Not to mention using an edge on plywood's. Talk about an edge killer!!! The fact that as you state, you used this tool to "work over" your chisels and havn't used it since, tells me all I need to know.
The advantage that most power sharpeners bring to the table is that they eliminate the repetitive motions of sharpening using a wheeled honing guide or even freehand. The limitation to these tools was the available PSA grit mediums. As these machines became more popular and affordable, the aftermarket followed suit with numerous options. DMT even has a diamond disc available now. Using the right progression of grits, proper technique and setup. these machines can give you an edge comparable to anything out there, except "maybe" the high end water stones.
The reason for selling this is that I went back to the scary sharp method. Oddly enough, I enjoy sharpening, I dont mind the sweat an effort required to put on a perfect edge using a honing guide. The trade off between sheets of PSA micrograined papers and PSA micrograin disc's is about a wash in terms of cost and amount of materials used. I have a complete Lee Valley MKII system and the cost is in the same ballpark as the WorkSharp3000 with accessories. Within the last couple of months, I've broken down and bit the bullet and invested in DMT diamond stones. Very pleased thus far I must say. So far I've done a half dozen block planes, half dozen bench planes and another half dozen chisels. Once I do my beater chisels, I may do a review on em....
The area where the WorkSharp3000 and other power sharpeners for that matter shine is when it comes to tuning up lathe and carving edges. This aspect of having a WS3000 will be missed. Would love to spend a weekend with a Tormek T8. Just to see if it lives up to the hype. Judging by the reviews, it does.
In the end IMHO, methods such as waterstones, wetstones, power sharpeners, scary sharp etc. all are quite capable of achieving an outstanding edge. With perhaps the only exception being waterstones in the 20-30,000 grit ranges. No doubt that is a much, much finer edge, but one whack with the mallet or one hard push into sugar maple and that 20-30,000 edge quickly becomes a 5-10,000 edge...I enjoy putting on a high end edge, I just don't think I enjoy it that much
