Sorry to here about your knife. I'd try to contact Ontario about it.

I have to say, I don't think you should dismiss this knife as being a good knife. If it's an RD and anything like Justin's RD6 that I have, the tip is probably thinner than a lot of Busse kin knives. I just checked mine out compared to my S5, and the S5 has a thicker tip. I'd say that it's just a part of the design, not a flaw in the steel. Keep in mind that the SarQ is a saber grind which makes for a thicker tip. Any of the DM knives have pretty thick tips, too.

Again, sorry to hear about your knife!
