Once a hand-carver always a hand-carver, power carving tools have a totally different vibe (literally), so, I concur regarding switching to rotary power carving, and when my time comes I too would rather put away my gouges than switch to power, 'though I believe the Inuit had a saying , which goes 'when your teeth are gone, learn to like mush...' :-)
Do your comments mean the crappie is totally knife carved?
