Good attention

The best summa dealer in the USA

Great blades

I've tried for years to avoid the extra expense of genuine Summa Blades. They are much more expensive than generic replacement. I've finally come to the conclusion that they last much longer, consistently fit properly and are worth the extra cost.

Best blades for a Summa T cutter

Very few choices for aftermarket blades for a Summa tangential cutter. The ones from Summa are the longest lasting but at an extreme price premium.
