I've always wanted one of these, since I learned about them back in the '90s. That's moving pretty quick for a 230 grain .45

1200 ft lb of energy out of a pistol makes me hand flappingly happy.

I haven't shot it much, maybe two magazines. So far the accuracy and reliability are good, which exceeded my expectations considering it's an Automag, the Ford truck of the handguns. ¯\_(ツ)_/¯
 
Random thought:

Do not let an imbecile power sharpen your Delta 3V. Or, for that matter, any knife you care about.

Got this old girl back to the mothership for some rework. I tested the edge against some known standards and, despite being more obtuse than my normal edge geometry for this test, it rolled pretty bad and is clearly burnt.

Going to have to set it back a bit to get back into the good Delta love
 
A customer had a knife shop sharpen his knife for them and they made a real mess of it. It's tempting to post their name online to prevent other people from getting their knives sharpened at this shop.

It usually takes bright light and magnification to see edge roll in this particular test, but it's plain as day on this one.

I could strangle that operator because this has my name on it and someone might think I don't know how to heat treat a knife.
 
It doesn’t matter how many times you say it, or what examples and evidence you point to.


There’s always someone doing it.



My favorite is the ol’ ‘I use a worn out 600 grit belt - gives a fine finish and a toothy edge’.
 
I like to tune up the edges of my knives by hand using Japanese water stones...

I'll usually start with a medium 1000 grit followed by a fine 4000 grit and I have some super fine 5000/6000 grit stones as a further option for light stropping/finishing of edges.

I'll maintain knife edges with a leather bench strop and sometimes I'll strop with a sheet of brown kraft paper over a rectangular glass plate on a table top.

I may not be the best at knife sharpening skills but I seem to get by ok.
 
I ordered some extra hard Japanese style water stones to try out for our sharpening process here, but they would wear down too fast for our process. They don't tolerate a nasty burr of Delta 3V too good.

Of all the things available in this high-tech world, an enormous white Arkansas stone has been the answer.

It has to be dressed every day.

Uneducated question but why not buy something like a few Tormeks with diamond wheels?

We're not doing the entire process on an Arkansas stone silly goose

A Tormek is a good system and I would encourage people to use something like that, however the system that I use is better.

You're still going to have a burr, regardless of the system you use. And the best way to remove that burr is on a stone.

So... looks like a Tormek T-4 runs at about 2100 linear inches per minute, wet, if I'm mathing correctly. Would the same linear speed on a wet belt with similar grit also be ok for delta 3v? Not that I have either, just trying to understand the options.
