Andis T-Outline:
T-Outliner® T-Blade Trimmer | Andis
It can replace both the T-blade:
Superliner Replacement T-Blade | ANDIS
and the standard blade:
UltraEdge® Detachable Outliner® Blade, Size 1/150 | ANDIS
It depends on how "close" or "zero gap" you want for your trimming needs. I used so many trimmers in the past, I gave up and return back to the Andis.
