Super useful blades
These blades are the best! I find their flexibility to be immensely useful when flush cutting. Olfa if you read this please make these solid blades in the 25 mm size!

They last a long time
The solid blades are great! Very durable! The snap offs are good as well-when the blade tip becomes dull you just snap off the full part but if your not careful with how much pressure your using when your cutting they snap when and where you don’t want them to. I use both but mostly these solid blades because they’re more reliable

Excellent for removing silicone/butyl/caulking around/under fixtures in RV
I reviewed the Olfa 5003 L-1 18mm Ratchet-Lock Heavy-Duty Utility Knife and mentioned this solid blade, but just realized I never reviewed the blade here. The knife with this blade is perfect for working on my RV. It is long, thin, and flexible, which is exactly what is needed to slide under a fixture (door, water heater, lamp, etc) to break the usual silicone/butyl seal. I was able to slide the blade over an inch deep when removing my rear door (the factory really spread a lot of silicone for that seal). Then, using some vinyl lockout wedges, I was able to pry the edges around the door frame up without ever scratching my fiberglass gelcoat. Highly recommended if you do work on your own RV (or boat)!

Okay blade
Was hoping since the blade was solid it would be thicker and stiffer.

Hard to get in stores !
This is a blade that lasts forever, doesn't break off just when you really need it!

Sharp blade
It is what's described, single pieces of replacement blades in a small box. Needed to use the entire length of blade so didn't need snap off sections, and no snapping is safer on use.
