New Pricking Irons Dull?

[Tugadude]

I found this information in the product description.  So apparently they intend on them not being "too sharp"...

The Amy Roke pricking irons are all hand polished to allow the teeth to pierce the leather really easily and slide out without and issues. They also have a carefully tested design to not cut through the leather too sharply but rather create a nice rounded opening. This helps ensure as you stitch the thread doesn't pull out leather fibers. 

Also, the picture shows to my eye a sort of blunt finishing, almost rounded.

I'm new to leather working and just recieved some of my tools in the mail. I got an 8 tooth 3mm Amy Roke pricking iron, along with a 2 tooth. The 2 tooth works perfect, but the 8 doesn't seem to go in to the leather to mark it, it looks as if the teeth are just pushing the leather down, if that makes sense. Is this normal? I guess since there is more surface area it may be harder for that many teeth to pierce, but I dont feel like this should be an issue.

Should I go ahead and just gently polish each tooth, making sure to not change the angle obviously, to try and get it to pierce rather than just push? Am I crazy and just doing things wrong? Any help is appreciated.

If you intend to punch the iron all the way through the leather then i'm afraid you bought the wrong tool. As @Tugadude said this is not what the amy roke pricking iron is intended for. They are like the old pricking irons which are only ment to mark the leather. What you should have bought is sometimes described as a hybrid pricking iron. These are sharp and able to punch all the way through. Wuta and kevin lee and almost all of the highend chinese pricking iron are like hybrids.

I am also very new but I use stitching chisels as pricking irons to mark the leather and actually pierce with a sharpened awl. The pricks guide the awl. 

 

I didnt like the uncontrolled smooshing that the Tandy chisels did to the leather when hammered in, so I just use hand strength alone to prick my stitch marks in.

Stitching chisels certainly can be used as a conventional pricking iron and some pricking irons can behave like a chisel.  For that matter, a kitchen fork could suffice so long as the times weren't bent.  If the leather is quite thin, the C.S. Osborne and Blanchard pricking irons will cut all the way through.  The thing to watch out for is that their teeth are tapered and in thicker leather, by the time they would penetrate, they would leave a gigantic hole that will not close up properly.

Same holds true for awls.  Controlling the depth with which you push the awl through the leather will provide consistency but if you only stab part-way through on some and all the way through on others, you will have odd-sized holes and irregular stitching.

So there is a lot going on and a lot to be aware of, hence the fact that in order to get really good at saddle stitching you have to work out the details.  Then repeat them!
