I've contacted LM about a blade for my Flair and was told they don't have any blades for that platform anymore.Not sure why it is disappointing to get a Rebar($100 value where you're at) for a $20 broken parts PST.
You could try contacting Leatherman directly and ask if they have parts to repair a sentimental PST. We have to pay for shipping to Leatherman here in the states.Or you could look this this way you now have some spare parts to use as backups or for modifications
Even if you do not want the Rebar, it is more than a fair deal, in my opinion. You can get two PSTs on ebay for what a new Rebar costs. Or just trade the Rebar for a PST or something. Or give the Rebar as a gift to someone.
Probably a member here that would trade you a pst for a rebar, worth a try
