Concave Jewelling pushers

[Neverenoughwatches]

Hey all watch peeps, we all ok ?

After my recent acquisition of a seitz jewelling tool, I'm wondering if i should boost its accessory armoury. The set didn't contain any concave pushers so my question is how useful would these be compared to flat and pump pushers ?

Honestly, I have never used my concave pushers in 8 months of having my jeweling set.  Flat and pump are a must.  I think the only time you use a concave is when you are pushing domed jewel from the domed side.  This might be more common in vintage American pocketwatches.
