a first clamping arm carried by said at least one guide rod on a first side of said housing and movable along said guide rod;
a second clamping arm carried by said at least one guide rod on a second side of said housing opposite said first side and movable along said guide rod;
said first and the second clamping arms each including a securing arm portion extending at an inclined upward angle above a horizontal plane of said flat top surface; whereby the blade of the hand tool is receivable against said gripping material of said flat top surface and said clamping arms are movable along said guide rod to engage said blade and press said blade downward against said gripping material on said flat top surface of said housing.
15 . A honing guide for a tool sharpening system, said honing guide comprising:
a housing having a flat top surface;
a gripping material carried by said flat top surface;
a roller member rotatably carried by said housing;
at least one guide rod opening disposed in said housing and passing completely through said housing;
a clamp removably carried by said housing, said clamp including:
at least one guide rod received in and extending through said at least one guide rod opening, wherein said guide rod extends laterally outward from said housing below said flat top surface;
