Does the T1 Tomahawk have Replacement Blades?

Yes, the T1 Tomahawk contains blades that can be replaced by the user if they become damaged, worn out, or broken.  Replacement blades come in English (inches and feet), Split (Inches and Millimeters), and Metric (millimeters and centimeters). 

Any replacement blade will work with any T1, regardless of which type of blade it originally came with (i.e,  if you bought a metric T1, you can later install a split replacement blade in it)
