Does my CS Spartan need reprofiling? each side of the blade is a different angle

My Cold Steel Spartan blade seems to have a different angle on each side of the blade. I'm including pictures of it, but it's extremely hard to capture it in a photo.
I bought it from someone here at BFC so I don't know if they sharpened it wrong or a previous owner did or even if it's supposed to be like this. I honestly have no idea.
Do I need to or should I do something about it?
Thanks!

The picture on the left is blade up.
The one on the right has the blade facing away from the camera, so you're only really seeing the back edge of the tip of the blade.

My quick take is either the previous owner a lefty or did an asymetrical bevel reprofiled. If it bothers you, just re-profile the bevel so the apex re-ligns to the mid/center again.
 
As a right hander I prefer symmetrical edge or asym the other direction, so steering favor going straight rather than early exit the cutting material.

Okay well I tried to sharpen it on my triangle sharp maker and on the left side (the more-regular-angle), it made a high pitched like screechy scratchy sound and it just kind of glided along.
 
A lot of CS products come with shoddy, off center grinding. Yours seems to be worse than most. you can re-profile it with your Sharpmaker starting with the coarsest grit or try CS customer service.Good luck--KV

That's disappointing. I thought cold steel was so cool with all their cool knives :'(
I'll shoot them an email (I couldn't think of any good knife puns, so it's a gun pun)
 
Cold steel makes a good knife its just surrounded by a lot of over the top marketing and a owner with a giant ego. The products range from ok to awesome it just depends on what you are looking for.

The asymmetric edge is typical and I get a feeling it might be their way of creating a high degree of sharpness and out of the box Wow! Factor. Luckily the steel they use is often easily sharpened so correcting the asymmetric edge should be fairly simple with even basic tools.
 
No offense but I started collecting knives with mtech and gerber survival knives and some china cheapos that cost like fifteen bucks each. Then I saw the cold steel Spartan which has an epic look and aus8 which I though was some supermetal since the knive cost a whopping 100bucks(Singapore dollar)!!I used it to cut a single piece of carbon fiber and some cardboard and the edges got a bit dent coz it rolled over at the belly point.It can no longer slice paper at the belly point coz its a bit dull.
Am I expecting too much from the knife or is it a factory defect? Feels like the metal is bull anyway since I have no idea how to sharpen the recurve knife with a rectangular sharpening stone..any tips?
 
Aus8 is a basic stainless steel and by todays standard its far from being a supermetal.

$100 is expensive to some and entry-level for most of us here.

Rounding the corner of a stone slightly will allow you to easily sharpen a recurve, Your blade is not defective it just needs to be maintained.

Work on the other side. Use a sharpie to color your edge. Start at 40* or 30* - whatever wipes off that sharpie line nicely. I would sharpen the off side until it matches the side that was making the noise. It sounds like you just have to be patient and remove metal from one side until it matches the other - then go at both sides evenly. Hope that made sense.

Crimsontideshooter made this video that should help convey what I'm trying to say. :thumbup:

I would add one small item to that well done video. The narrator only mentions bevels with mismatched angles, eg one obtuse and one acute. You can however have a perfectly symmetrical bevel that is off center - it means that the point at which that bevel meets the primary bevel is higher up the blade on one side than the bevel is on the other side. The solution is the same as the one well described in the video - sharpen more on the smaller bevel side than on the large bevel side. Make sure to keep the correct angle and let the point move back to the middle.

But just be aware that you can have perfectly consistent angles in your technique, but were just heavier or did more strokes on one side than the other. Otherwise you might end up chasing the angle back and forth, the critical part is having the same angle on each side.

A picture is worth a thousand words, but I don't have the resources at the moment to draw this out. If what I said is not clear I can try to make a drawing and upload it.
