There are good period knives out there that are more than suitable for your needs.
Two 'very' good sources are gun shows - and flea markets.
You'll want to be looking for carbon steel blades - commonly found on butcher knives.
The one 'drawback' on those is that all too often - they've been sharpened far past the point they should - atypical for a 'working' knife.
But - this end of Nebraska was a meatpacking area - so finding suitable cutlery should be no real problem for you.
Dixie Gun Works has some very good knives - new-made and some new-old-stock, I'm sure.
They have a good online catalog - so take a look.
Hell - buy a copy - since it has a wealth of information.
I have three really nice utility knives of the style used for trade - a Green River skinner made by Russell, a period 'Camp Knife' 'probably' made by Russell and a 'Trade Knife' - made by Jimmy Coleman, of Powell, Wyoming.
All would've been common to the era - with about 5 1/2" - 6" blades.
Dixie also has kits - in case you're so inclined - email at -
www.dixiegunworks.comThe pocket watch is another matter - and prices vary wildly.
Lower-priced ones can be found reasonably - but having an early watch Cleaned and Oiled and Regulated can cost a couple of bucks and take some real time, should a part be missing and require locating.
Good old ones are pretty cool, though - much more 'satisfying' than a modern one with a quartz movement.
Again - look at the antique malls, flea markets and such and you'll turn something up.
Lincoln has several - as does Omaha - and I've seen some decent ones all ready to go and cleaned, for fair prices.
Good Luck.
Vaya,
Scouts Out!
