could anyone who owns a 10 inch ontario machete tell me what you think of it? the tip looks too rounded to be able to chop with at all. exactly how thick is the spine? any chipping ever with the 1095? im basically comparing the rtak and economy machete because these are my final 2 choices for large knife. how is its edge retention? does it seem like its had a proper temper? anyone have pictures of the spine?
