Sharpening options for creating a new edge on a knife/dagger that was never/has never been sharpened:
Lansky Puck
Lowes basic whetstone
Wästikivi Eräkivi whetstone
Spyderco Tri-angle Sharpmaker with 3x rod grits
File
Sandpaper various grits on a wood block
DC3/DC4


Got this great Tod Cutler quillion dagger replica and ordered it unsharpened thinking the edge would be an easy thing to put on... using the sharpmaker, managed to get some sort of 40* edge but ended up scratching the blade up badly getting the correct angle... any recommendations on getting those scratches out? The only power tool is a bench grinder and want to avoid using it... but at this point it is already scratched up to heck.
 
For initial edge setting, you want something very coarse. If something like a belt sander is not an option, then your most coarse hand tool is the best one. The file is probably your best bet.

Consistent angle control is important in making a clean bevel. If you can clamp the blade down and then use something like a block for reference, you can probably keep a fairly consistent angle using the file. Something like this Paul Sellers method would be a good place to start:


When making big changes in blade geometry, you don't want to do too much at once. Don't work on one side for a long time. Work one side for a minute or two. Then switch and work for a minute or two. Then switch again. It's also very important to OBSERVE your progress as you go and make adjustments if you are not getting what you want.

It's hard to give advice on the scratches without seeing them. A ScotchBrite pad might blend them in nicely. But it very much depends upon the finish that is already on the blade and what finish you want to end up with when you are done "fixing" the scratches.

Good luck.
