I'm saying 45 degrees and offer to allow you to borrow my long nose pliers to crimp those staples. That's really a nice nickel too. Very well struck and not beaten. Looks MS to me! If you ever snag you a flat clinch stapler, the MAX brand has some good ones and bad ones. Some of their better appearing bad ones are perfect for stapling flips with uniform precision, but, their staples often have to be purchase on ebay from Thailand, the UK or Japan and the tricky SOB's make some of those staples only sharpened on one side so they absolutely will not staple through 75-150 pages, or a coin flip without much cussing. MAX does make a conventional desktop (no long lever arm) that uses conventional staples and it works pretty well. I often staple memo's and briefs having up to 200 pages so I learned this the hard way. The correct staples for my HD cost about 15 bucks for 1000 regardless of which 3 lengths I want. The short 6mm (about 1/4") sharpened on both sides do flips effortlessly and precisely. It has an adjustable guide whose opening is just under 2"... works well. Then I think I snagged a lever arm Swingline that uses special staples that no B&M stores seem to keep in stock. They are cheaper than the MAX and easier to find online with no 'sharpened on one side only" tricky versions of those staples offered. ebay and cheap, do your homework first, you should have a nice stapler... ;-)
More than I EVER, EFFER wanted to know. Now I have blueprints for almost every staple ever made and available for sale. I acted a little ugly in OfficeMax when the person on the phone assured me they had my staples (gave them the complete and full mfg's reorder and stock number) in stock so I drove 45 minutes there on a Sunday and they were WRONG, couldn't even order them. Corporate sent me a nice in-store credit, which was pretty nice. I had to get 5 copies of many pages in a box before 7AM the following morning, otherwise, I wouldn't have cared one bit and bought something else while I made fun of the twit that needed some training. She was cute.
Yes I see the staple is upside down. That same staple should be at the bottom of both photos. 45 degrees.
That assertion is a bit confusing despite the correct conclusion of 45 degrees. To determine degrees of rotation, the southern-most staple for this one's first picture should land northern-most to properly calculate reverse rotation. 6 o'clock should move to 12 o'clock exactly how she did it the second time.
