The "Dirty Harry" is quite a rough one. We let the metal filings stick out. That way we get more filings in and in total we get a more powerful buster.

So, please understand: They are not meant ot be pretty!

And that's why we called them "Dirty Harry" in the first place, after Clint Eastwood's iconoc role as "shoot first, ask questions later" cop. 

So here you get 50 of them for 30% off which is a great deal.
