I have a modern Stanley 45 (all the improvements, so to speak). The slitter blade was never sharpened or honed, and I notice that the blade has four bevels which yield a rounded “arrowhead” shape. The tip is rounded rather than a point. My guess is that is for strength because a point is more likely to break off. I notice that the four original bevels are convex, and not flat.
So I would like to sharpen and hone this slitter blade. I have searched the internet for any info on how it should be sharpened, but have found nothing. My guess is that I should sharpen and hone it so that it retains its original shape, with a rounded nose, and with four convex rather than flat bevels.
Is my guess correct? IF not, then what?
If there is information out there somewhere, please just point me to it and I’ll find it.
I have not been able to find any info on using the slitter, other than the few sentences in the Stanley 45 pamphlet. Does anyone have any info on how thick a board that this slitter is useful in cutting, or how wide a cut it can make. I have read that it is for cutting off narrow pieces from a board. OK, how narrow?
Or more simply put, do you have any suggestions for the sizes of boards to make cuts from, and the size of the pieces cut off?
I am sure all of this ground has been walked on a million times. I wouldn’t have asked here without having tried to find the information on my own.
Also, since I am new to the Stanley 45, I would appreciate suggestions from folks with real experience on things that they have found it useful for doing, and things that they have found it not useful for doing.
Thank you very much.
PS I have read Patrick Leach’s words in his Blood and Gore about the problems with a #45. I fully understand the problems of tearout when you don’t have a ‘mouth’ on a plane. I realize the need to choose stock with fairly regular grain. But maybe someone has experience on which woods (eg cherry, walnut, poplar) that are better for the 45 and which may not be so good. I have read that maple is not. Maybe that referred to figured maple. Any thoughts are appreciated.
