Long term use

[Serval]

I do not know if this have been discussed earlier but my concern is about the 111mm series of Vics with the liner lock: Most of those models lack the liner to be on opposite side to the locking steel liner, i.e. there is no liner between the blade and (usually) the saw.

So anyone that have been using this type of knife for some time: is this causing any problem like vertical or horizontal play or do perhaps the blade rise compared to the handle (fold out "too much").

I wonder this because the force at the rivet that holds the blade must be huge when using the blade and might bend the rivet. I assume those are made of brass as usual.

This is also true for the slide-lock 111mm models (in particular the hunter, my favorite) , but there the two layers that lack liner between them is the saw (low force at use compared to blade) and the combo tool (very short, lower momentum)

Hmmm.  I'm not sure I understand your the concern.  The rivets in these are 3mm at the ends so that's pretty strong.  Maybe more important to your question, if I understand it correctly, is that the locking liner is steel and it's right next to the blade and make the knife very rigit allowing the locking driver to really function as a small pry-tool.  There does not really seem to be enough force required on a cutting edge in the short distance between the blade and the outer liner which is inly the width of the tang on the saw.  I'm pretty sure there is zero issue here as the steel liner and the large rivets certainly make this the most robust SAK ever.

+1. I have had two OHT's for about 1.5 years now, and they are just as solid as when I got them.  They see a lot of use (no abuse, though). 

Although, I too am unsure exactly wh :think:at you are asking

Yeah I was somewhat tired yesterday, so perhaps my post was not so clear. But on the other hand I got the answer I wanted, many thanks for that.

The reason I asked is because of my Forrester. I am planning to try a small mod for it, and if there was any issues about the rivets I would also have to make an extra liner to put between blade and saw. That knife is so fantastic so I would prefer it to stay in shape even after years of use!

The tool that is most at risk of failure in the 111mm line is the backside Phillips. The brass pin and aluminum liner configuration is fairly weak.  If you try to use it as a T-handle driver, it will fail--period.  The driver will pry the liners apart and then cut through the brass pin.

used the old OHT for a couple of years, and didn't notice anything like that. I used it very often, but not abusive use.

Thanks for the link, somehow I missed that discussion the 1st time around.

My primary use for the OHT is the OH blade and the saw (woodsbumming and such) and I consider the tools a nice bonus if needed.  Now I know to be careful. 

I do think one of the benefit of such tools on a SAK is that they are available if needed in an emergency.  Even if you destroy the knife in the process SAKs are cheap enough you can replace them without losing a lot of sleep over it.

Oh, I forgot to ask, do you think the pins on the alox knives can withstand more force?  I think I recall reading that they are different than the normal brass pins.  Although it may be hard to compare as there are no back-side tools on the alox.
