This has two tips. One is smaller for details.  However there is not really much difference in the sizes.  It feels great in the hand and is fairly easily too use.  I use it to trace images onto canvas with transfer paper.  It prevents me from damaging my original sketches to bad so I can reuse them.  This can also leave groves in soft wood. So if you use a wood burner you can engrave a picture in the wood to go by.  Honestly this is a simple and handy tool that can be used for multiple things.

I have included some picture showing the two tips, and a size compared to my hand.  Hope this helps. Happy Embossing! :)
