Line trimmer blades

[Knots]

Does anyone know where I might find some 9 or 10 inch four cornered blades for line trimmers. I believe the arbor size is 7/8 inch.
It is to fit Shindiawa T-25, T-20 trimmers, etc..
Can’t seem to find them anywhere. Used to be everywhere.
Thank you,
Knots

Pardon my ignorance, is that pre cut nylon line or flail type blades?

Picture of what You are looking for?

No, these are metal blades about 1/8 inch thick . 4 blades with a leading and trailing cutting edge. When one set got dull you just flipped the blade. Would easily cut material up to about 1/2 inch and would not grab a round wooden post as long as you kept the speed up. Much faster and neater in rough stuff than string.

So it is a solid steel disk for brush cutting?

Do You have a part number for those You used so far?
My Dolmar ones have part numbers stamped on them.

Something like this?

Not flippable, but I found these to be less aggressive and their heavier weight cushioned impacts.

Stihl but I am betting your bore is not 0.875 and it is 0.787 or 1.00

Did you find what you wanted?

Curious too!
Those should be everywhere in various designs.
