Lilith is a great gal and will be able to help out with any questions you have, What a cool gift!!
Paste or a barber hone can help "refresh" an edge that is losing it's sharpness. Personally I do not use them, but I know a few people that so and they do work, You need some type of fabric strop to put this on. An old jeans pant leg would work, just make sure the seams are cut out.
Have a great Christmas and feel free to pm any of the girls if you have questions
