So what is the difference?

I will be taking a joinery class this summer and the tool list for the class includes a Nicholson #49 or #50 cabinet rasp.  I have 2 Logier rasps, a #9 and a #13.  How do I compare the courseness between these 2 grading systems???  In other words is a #49 simliar to a #13?  Tanks for you input.

Did you try to Google the difference?  If not, try calling the class.

You could have just said that you don't know.   Googling hasn't helped....yet.  I called the class and they said that my Liogier rasps would work just fine.  But I would still like to find a comparison chart just so when someone asks me I don't have to say. "Try to google it."..................You know that I'm just messin' with ya...

So this site https://www.jamestowndistributors.com/userportal/show_product.do?pid=2778 lists the 49 as a 2nd cut and the 50 as a smooth cut. The Logier #9 is a medium coarse cut so similar to the 49 and the #50 is a smoother cut so similar to the #13.

My guess is their intention is to have a medium for faster removal and a slower removal for detail work. Companies don't make this easier i like how gramarancy does this and just lists their estimated tpi. I don't think you can get any more clear than that.

There may also be some degree of referring to the Nicholson #49 and #50 as a generic reference.  They were the typical rasps one came across for so long.  Kind of like referring to a circular saw as a "Skilsaw".  It took me several tries to get a #49 from Jamestown Dist that didn't look like it had been stored in a bucket with a dozen others (mached sections of teeth).  I'm sure your rasps will be fine.

Really?  I spent half my life thinking a jigsaw's actual name was a "skilsaw."  Never knew of a circular saw as one.  Maybe it's a geographical difference, like "soda" vs. "pop," or maybe it was just my dad.

I think that’s a regional thing. When I worked at a hardware store, half the people asking for a ‘skilsaw’ meant jigsaw, the other half meant circular saw. 

A guy I worked with always said “There are ten names for any one item and eleven of them are wrong.”
