Which stylus is correct for a Shellac LP

I found some older LPs which I believe are shellac (because they are stiff, not "bendy" like vinyl). Should I use the wider 78 stylus (3mm?), rather than a stylus typically used for LPs, (eg., .08?) because of the physical composition of the record? I’d rather know in advance than experiment and ruin a record, or a stylus.

+1 Elizabeth! I have an early Sonny Rollins pressing just like that in mono from the early 50's. Same groove width as all LPs.

The groove width of a 78 compared to a 33 and 1/3 LP is readily apparent to the eye! No need for a magnifying glass!

"The eye" is relative, (or at least mine is no longer that objective), but I take the reasonable explanations offered - thank you!  I only asked in the first place because I was always taught the rule of thumb: Stiff = Shellac and 'Bendy' = Vinyl.  I actually have a quite a few stiff LPs.  Do I now I have to worry about using a mono stylus for those playbacks instead of the 2 channel stylus I normally use?

There were 78s recorded with the 'microgroove' process. They are very much the exception! And they will say 'microgroove' on the label.
All LPs use the microgroove stylus as Elizabeth pointed out.
