No I dont use them all the time just once in awhile. They are 8 and 3/8 inches long by 1 and5/8 wide by about 1 1/2 tall. and yes they work really well. The only thing I did wrong with them is the mouth is open way to much and I need to put a filler piece in them to close the mouth.
Dorje, None, I was watching David J. Marks on Woodworks on DIY. he had a show on making hand planes some years ago. So I went out to the shop and started making them. I know they are some what different then what most planes look like but I like the way they fit my hand. They work very well.
