Deburing Tool

I have seen several on the forum machineing and building there own part for Airforce guns and others. I was a machinist for 35 years and this little tool is great for deburing inside holes and outside of parts after milling or lathe work just thought I would pass it along maybe you guys allready have one,
if not you need to get one. The sight listed is only for ref you can get them several different places. The one with the yellow handle is similar to what I have the bigger the handle the better!
