FYI - Was advised X-Acto razor saw specifics is proprietary... - Model Railroader Magazine

I need to replace a worn 30 year old X-Acto razor saw blade and the X235 product packaging found at my LHS that "looks" like what I need but didn't include the number of teeth per inch, depth of cut and length of the blade info on the packaging. So, I emailed X-Acto customer service and this is the reply I got (and note no name attached):

"The information you are looking for is proprietary. The Kerf is  0.018"

How stating simple dimensional information I asked for for the X235 product is proprietary yet provide the specific kerf dimensional info I didn't ask for is beyond me, especially when the number of TPI, depth of cut, etc., is commonly found on the packaging of any hacksaw, jigsaw or circular saw blade at any hardware of big box store.

Heck of a customer policy for anyone in this hobby in particular. Unbelievable.
