Reddit reviews Columbia River Knife & Tool CRKT Minimalist Bowie Neck Knife: Compact Fixed Blade Knife, Folts Utility Knife with Bead Blast Blade, Resin Infused Fiber Handle, and Sheath 2387

I could sell you my CRKT minimalist bowie that's been barely used. It's a fantastic little knife but I don't really have a use for it at all. I'd let it go for $15 shipped.

I would avoid all of the ones you linked, they are all low quality brands except the last one you linked but it's a ceramic knife that can't be easily sharpened. I linked some better option bellow.

I don't own one personally, but it seems like the CRKT Minimalist Bowie would fit the bill. It comes in a few other blade shapes too.

Edit: just noticed you wanted the handle shape to be relatively the same, so maybe this isn't the one for you, but still worth a look.

I have a few CRKTs I carry normally.

The two I carry most often are the Eros for nicer occasions, and the M16-13ZLEK for work/everyday use.

The ball bearing system on the Eros is super smooth, and the M16 feels sturdy enough for anything I normally encounter on a job site (construction inspection).

I also have the Bowie Minimalist which I tried neck carring, but did not like. I am looking for a belt clip or something of that nature instead.

Lastly, I have the Ignitor. I wouldn't recommend it due to the difficulty in using the Fire Safe stud and the frame lock in this model. It is possible my particular knife is an outlier, but the thumb stud release is very hard to depress and flick. The frame lock on this model is also very hard to unlock. I think that this is due to the Out Burst spring putting pressure on the blade and frame lock when the blade is deployed. I cannot operate this knife with one hand like I can the other two folders mentioned.

Honestly though, for under $100 dollars, you can find a better knife. I carry these because they are around or under $50, and I broke the tip off of my Kershaw Blur.

The minimalist is 25.50 new from Amazon, so you might want to adjust that price. GLWS

Available for 25 on Amazon http://www.amazon.com/Columbia-River-Knife-Minimalist-2387/dp/B0030IT76C

if it has to be fixed blade your options are pretty limited

the only one of these i've owned is the becker necker, which is great, but the sheath is so big that it pretty much cancels out the small size of the knife.

I really love the three finger grip on this one https://www.amazon.com/Columbia-River-Knife-Minimalist-2387/dp/B0030IT76C/ref=sr_1_1?ie=UTF8&qid=1487532167&sr=8-1&keywords=crkt+neck+knife

The CRKT Minimalist is a pretty neat little knife.
