I got my 2 blade orange Hayn' Helper today. It's a pretty substantial knife. The pen blade is as thick as the main blade (as is the spring), which gives the overall thickness about that of a dime, and a significant heft over a single blade (I don't have a single blade Hayn' Helper, but I do have a Bull Nose). The "pen" blade is also pretty long; nearly 2" of cutting length. Both blades have half-stops.
Overall F&F I'd give it an 8.5 out of 10. The blades are rock solid, which is what I mostly care about. The springs stick out a bit at the half-stop position (on my Bull Nose the spring is sunk a bit), but who really cares about that? It'd be nice if they were flush of course, but nobody uses a knife in half-open position complaining about the springs not being flush is extreme nitpicking unless we're talking about a custom or something. The spring pin is nice and flush with the handles and doesn't snag when you rub your fingers against them. The lanyard tube looks a bit "deformed" at the bottom, but it looks like it's that way to follow the couture of the handles. Plus, the "deformation" likely gives less of a sharp surface to wear out a lanyard. I'm pretty sure it was done this way on purpose. The pivot pin isn't centered in the pivot, but I really couldn't care less about that. The knife is basically a reimagined 2 blade sodbuster, after all. The blade grinds are even, and the satin finish is even, with no tool marks that stand out. If you hold the knife up to the light with the blades open you can see a couple tiny cracks of light through the liners/springs, but when just looking at the back of the knife it doesn't look to have any gaps. Blades are perfectly centered when closed. Pull on the main blade is identical to that of my Bull Nose (a solid 5), while the pen blade is maybe a 5.5 or a 6, because the shorter blade has a bit less leverage. Excellent snap in both directions. The main blade can be pinched open pretty easily if you prefer. Out of tube sharpness on my example leaves some to be desired. Not very sharp, but the edges are ground really thin, so I'm sure it won't take much time with some ceramic rods to make them shaving sharp. I haven't used my Bull Nose much, but I like what I'm seeing from the O1 in the little time I've spent with it.
Perfect F&F? No. Acceptable for a $60 knife? Most definitely, and then some. I might tweak it a bit; the pen blade's tip doesn't stick out when closed, but it's only barely below the liners. If I move a piece of paper along the handles, it doesn't snag, but if I drag my finger with some pressure (the skin deforming and pressing into the handle), it can snag a bit. Filing down the kick a hair would probably eliminate this "problem". The main blade looks like it could be sunk quite a bit more without it hitting the backspring (to make it more pocketable), but doing so would obscure the nail nick behind the pen blade. I might tinker with this some in the future, with before/after pics.
My only real "complaint" is regarding the thickness and weight of the knife. It's a substantial knife. Almost too much so for me to want to pocket. The reason I got the 2 blade over the single blade is the same reason all (almost) all my traditional knives have at least 2 blades (one curved, one straight). But I would honestly probably be happier carrying the single blade version, since for my purposes, it's really all I would need (since I also EDC a SAK with 2 curved blades). I'll probably end up getting a single blade Hayn' Helper as well. Probably 2, actually, another one in orange, and one in the glow-in-the-dark acrylic.
Sorry, I can't post pics now. Well, I could, but they wouldn't be worth looking at.
