i realize everyone may have had their fill of the lcc topics, but i couldn't resist showing the two side by side since i have them both.
major differences include size and weight of course, and tip up for mt and tip down for lightfoot. the clips also 'curve' in opposite directions. mt has 3 aluminum anodized back spacers and a lanyard attachment, lightfoot has what appears to be a carbon fiber back spacer near the bottom and is mostly open down the spine, no lanyard hole.
