Hand held chamfer tools for de-burring

Apparently I created a dust-up in another thread
when discussing the use of 45* chamfers
for finishing the non-cutting edges of a blade
(a/k/a spine and choil).

In any event, to atone for my sins , as It seems these tools and techniques are not well known,
I thought I would share something that may come in handy to people here in this sub-forum.

For those outside the US they are sold under many brand names, including Exact.
Check your local markets for options relevant to you.

Please note that these tools are hole-making tools,
and obviously not intended to be used on edges or to be a part of that debate.

Just handy tools I thought someone may like to see if they are not already familiar with them

(The video is in the context of making knives of course)

Interesting. Have you used the deburring tool on a spine or choil? How does it compare to using a file?
