I had a friend sharpen my HTM DDR Mad Maxx 5.5 dlc, and while the edge came out great, he managed to round off the tip. I am only an ok sharpener, hence letting my friend do it, as he has sharpened knives for me in the past with no issue. I'm wondering what I can do to get this right, am I able to order a new blade, or send it in to get it reground? I appreciate any advice from those who know
