Andis T-Outliner Replacement Blade, Carbon Steel (04521)

Andis item 04521 is the carbon-steel T-Outliner replacement blade for close outlining and detailed edge work. Its shallow-tooth T-shaped profile is suited to defining lines and working in confined areas where control of the cutting edge matters. It is a replacement cutting component for compatible trimmers used by barbers and stylists.

The precision-ground carbon-steel construction supports sharp cutting and smooth hair feeding. Andis identifies GTO, GTX and GO as compatible models on the current product page and packaging. Confirm the model code on your trimmer when selecting the blade, especially when maintaining older equipment with a similar product name.

The manufacturer states that this blade can be zero-gapped. Any adjustment should follow the trimmer's setup instructions so that blade position is checked before use. The blade is made in the USA using domestic and foreign parts.

Regular maintenance remains part of keeping the cutting assembly ready for service. Brush out accumulated hair, clean as directed and apply blade oil between cuts. Wipe away excess lubricant before continuing with outlining or finishing work.
