Those are some really nice looking traditional carry knives, Hooker. Great job with the fit and finish and I'm sure you're nephew(glad he made it home) will get a lot of use out of his.
One quick tip to make you're life easier if you decide to do others. I hand sand my own blades and have found that up to 600 grit, plain old Windex does a great job in helping polish. A lot of knifemakers use it. Above 600 I use a thread cutting oil, and it does a good job of giving a really smooth finish. Always nice to see someone putting their skill and time
to good use.
