This is the exact same technique I use to finish my own high performance hunting / camping / survival knives: http://store.goughcustom.com/

I've been asked a few times to do a video showing how to satin finish a knife blade, so when I was working on my most recent batch of blades I put together this video!

The sandpaper I like most is Indasa Rhynowet 'Redline' sandpaper. I also use 'Sait' Saitech paper, it's very nice also and available to me locally.

If you want to order sandpaper in medium/large quantities then SuperGrit is your best bet. The sandpaper is inexpensive but very high quality, and service from SuperGrit is great: http://www.supergrit.com/products/Red...

You can also get the 'redline' paper in individual quantities from USAKnifeMaker along with anything else you might order from them:

The knife in my pocket this time is a Spyderco Manix 2 DLC: http://amzn.to/1Ii1Ke3

This video was shot using a Panasonic Lumix G6: http://amzn.to/1w1ISLi

Hope the video is helpful!
