Head/smoke shops, I think have the best digital scales. They have some that will weigh as low as nano grams all the way to pounds. Anywhere from $20 to $100.

I doubt they have anything that goes down to nanogram since that is 1x10^(-9) or increments of .000000001 grams. $1k+ analytical scales usually only go to .1mg or increments of .0001g.
EDIT-for reference a fingerprint on an object being weighed is about .0001g-.00005g

@OP,
Most UPS/FEDEX or USPS stores will have a scale sitting out you can use. It should be accurate enough, just make sure the knife is legal to bring in there, not sure if USPS has knife laws too

I use a Berkley hanging digital fish scale that I bought to weigh deer jerky. It weighs from 0.01 ounces up to fifty pounds, is programmable to ounces/pounds or metric. Cost about $25 at a mass merchandiser. The included battery has lasted over two years. Accurate enough for my needs.

I have a digital scale that I bought from the post office. It did not cost very much and is very accurate.
