I am starting f rom scratch to regrind and sharpen some old Buck Brothers chisels.

As I recall my reading about the trade off of bevel angle, the optimum for any given blade is a function of the "relative " physicals the steel; as I recall japanese blades are best sharpened to a different angle that European.

Does anyone know what the original grind angle was for Buck Brothers chisels, and whether this is the best choice based on current knowledge ?

Karl,

I have two set of old BB chisels.  They are sharpened to ?30?.  Keep in mind the "old timers" sharpened by eye and without a gauge.

Karl,

I grind many of my chisels to 25? as it slices cleaner thru the wood, especially on end grain.

Karl, I have three types of Buck Brothers chisels all ground to a different angle. I don't know if these are the original angles, but I haven't changed the grind while I have owned them. Square edge firmer chisels at 30, bevel edge butt chisels at 35, long paring at 20. I would also say that only a few of them are ground at those exact angles, most are off a degree or two either way from being hand sharpened.
 
Thanks everyone, for the feedback.

I think I will go for 25 degrees and be prepared to sharpen more often.

Speaking of "old time", I was trained to cut initial bevels on a very old slow-turning stone "grinding" wheel that ran in an oil bath; took hours.

Karl,
Since you asked, "Does anyone know what the original grind angle was for Buck Brothers chisels"

I have several New Old Stock (NOS) Buck Bros chisels, never used, original edge, and they are ground to 30 degrees.

For style comparison, they are socket, butt, bevel edge, much like the Stanley 750 chisels.
