Lots of opinions on this, but personally the Seb won hands down over the PT to me.
The Only area it does not win to me is in how the PT makes a killer little money clip, and is great just to carry free in your pocket. As with any Strider - they are just so absolutely cool looking. (Only the Hinderer XM18 look cooler to me)
If you are just cutting paper - you probably would never care if you swapped them out, but if you ever want to whittle - that rounded spine and hollow grind will be greatly missed on the seb, and you will also see a big difference in food prep (peeling apples etc).
You might also miss the thicker tip, if you ever see your self prying a little.
The clip on the PT is the lockbar stabilizer for that version.
I had a couple of instances with my PT, that I pushed hard on the back of the blade-spine and it closed on me - choil prevented any issues, but it still happened.
(although I have never had that issue with a SNG).
With a seb - the harder you push on the back of the spine - the tighter it locks up - fact.
Always remember - the reason why a Seb does not have a lockbar stabilizer, is because it is not needed due to the inside cut on the TI.
The above post was a correct statement concerning you might want to swap for a sng instead, actual blade length for a small classic seb is identical with a SNG.
My advice would be to keep your seb, and trade into a PT, or buy one - you will most likely regret letting go of your seb, unless you are getting into another one. - just my opinion.
The Regular small seb however is just a skosh shorter than the sng.
I have had 3 Striders - PT and 2 SNGs.
I have only kept one SNG - it is killer.
Have had 3 Sebs, got rid of one only becuase I just wanted a change.
Have beat the crud out of all of my sebs (batonning etc) - never any play.
The Striders that are gone however - I could not say that about - thus they hit the road.
Sriders are cool, but don't let the simple elegance of a Seb fool you into thinking they are not tough - for the "hard use" (to me that means wood working / cane making /batonning occasionally etc.) that I have put my blades through - I would choose a Seb over a Strider as my only knife everytime, but it took several purchases, and some disapointments before I came to that conclusion.
Good luck with your decision.
Be Well.
