Scogg (Sam),
Apologies for the late reply. Didn’t have thread notification on. I just wanted another data point plus I like to compare blade weights to get an idea as per its mass distribution, specifications, etc.
I found an appropriate electronic scale (to 1 gram accuracy) and sent it to Danny Massey at nihontocraft.com who measured this nihonto for me which came out to 17.4 ounces = 493.281702 grams.

I wanted to compare it to this other nihonto that I also purchased, which comes out to 625 grams.

Hope that clears things up. Thanks again for your reply.
Thank you to everyone for their replies.
Best regards,
