Thumb post on Nummzumm too close?

I've only seen pictures and have not handled the Nummzumm but it looks like the thumb post is too close to the frame. Looks like the frame would hinder a good purchase on the thumb post. Similar to the BM705.
Hope I am wrong. What say you people who have a Nummzumm.
 
Seems to me that it's in the place it is because it doubles as a stop-pin.

Kind regards,

The post placement is very well done, you have enough purchase between stud and frame and the opening "arc" is very fluid and natural. Bad stud placement can ruin a folder, if you have to push too far or can't get a good grab the knife becomes useless.
 
The studs serve as a stop, yes. Doesn't hinder the opening of the knife though. That's a good observation, they look like they might. I have pretty thick fingers and I find easy purchase when opening the knife. I also like that these are smooth studs as opposed to the pointy, ribbed ones from the Seb. I didn't dislike them but they were a little too sharp on the small sebs.

So far, I can't find anything that I dislike about this knife. It's just....right. Kind of how the Sebenza is just right. The only thing I'm not crazy about...kind of on the fence actually, is the sharpened swedge.....I could probably have done without that. I like conventional blades like the Sebenza more. BUT I really like the contour for your thumb. It's great, reminds me of the Busse Groovemaster. Don't really see that out there.
 
I agree with pbubsy. No issues with the location or use of the studs and they are easier on my thumb than those on the Seb.

There are only two things about the new Umnum that I think need to be changed.....

1) The screw for the backspacer needs to be flipped. I did mine as soon as I got it. Now the head matches that of the clip screw.
I've done this to all my Reeve's and know that many of you also do this; don't quite know why they still put them in backwards at the shop.

2) The swedge. Huh!?!?!?! Every time I grip the knife with the blade closed I feel like I'm going to slice one of my fingers or palm wide open. Now I realize that the swedge isn't fully shapened, so that is not going to happen; but why ruin the great ergos of this piece with what appears to be a brain fart in the blade profile? If you want to have a sharpened swedge, at the very least make sure that the shapened part is covered by the handle slabs when the blade is closed. Now I'm going to have to find someone to grind off anywhere from 3/8" to 1/2" of the swedge and hope the results turn out okay. I think they should...the new grind line should match up nicely with the primary grind line.


These are the only two things I haven't liked about the Umnum in the week that I've had it. It has become my EDC for work. I'd give it an overall grade of 9 out of 10. :thumbup:

All I did with the swedge was take the biting edge off it with some 1200 grit. Doesn't look any different and isn't sharp enough to cut you.
 
I always thought swedges were kind of hokey, until I carried a knife with one for a while. It's very handy to have a secondary edge that can be used to cut or scrape sticky or abrasive materials. This allows you to preserve the main edge.

The front of the spine is a handy location for the secondary edge.

I have not had any problems with cutting myself on a swedged Large Regular Sebenza; although I guess its swedge is a little mess prominent than the one on the Umnum.
 
I don't like the swedge on my LgSeb for this reason... so I used my sharpmaker stones to grind it down a bit... dosent look much different... actually, I think it looks better!
 
I have no issues with the thumb studs either. In fact they ARE quite comfy. The whole knife is incredible.
 
I agree. I've had no problems at all with opening mine. The urethane O-rings also help a little. I have put O-rings on both of my Strider AR's and it has helped immensely with them.
