    New Sage 1 - Is this normal?

    I just got a Spyderco Sage 1. The lockup seems "very early" - or "late" I don't know which is which to be honest, but this doesn't seem right. It seems that the lock should be further over, no? Should this be sent back?





    Thanks.

    That would be considered an early lock up, a desired trait by many, as it allows for the most wear/life of the lock. I personally prefer the lock to sit more central on the tang but there is nothing wrong with it, enjoy.

    That's a nice early lockup. The lock bar is fully engaged on the tang and as long as there is no blade play then I would not be worried about it. Some folks even prefer an earlier lockup.

    The lockup on my Cruwear Military is real early but it is rock solid and the blade doesn't budge so I'm happy with it.

    Maybe I'm wrong, but wouldn't an "early" lockup like that, fail faster than others bc of repeated closings, causing that tab to creep closer and closer to the "edge"?

    No, if anything, the lock will move towards the opposite scale under spring tension, as the face wears. As long as the bar makes good contact, and does not slip, you're good to go.

    My Sage 1 lockup looks just about the same, and it's been rock solid for almost 4 years now.

    Looks great to me. Sufficient engagement and oddles of room for wear.

    That is what I consider to be optimal for a new knife and what I would prefer for every one of my liner lock knives. The lock fully engages onto the tang of the knife and has the absolute maximum amount of room for wear.

    edit: on a second glance, it may be just slightly early, with just a sliver of the lock not engaging the tang. Flicking it open for a while may make it seat better in there and get it to be just perfect.

    That would be ideal as long as the lock up is solid.

    Glad you started this thread. My Sage-1 will be delivered within a couple hours and I'll be checking this out on mine.

    Thanks guys. Can someone explain to me though why, opening and closing it a hundred times, by obviously using your thumb to slide the lock over to the left to close it...would that not make the lock tab push further and further to the left over time?

    No, the opposite would occur as material is eroded at the interface between the lock bar and tang. With less material there, the lock will travel further to the right under the pressure of the liner lock, giving you later lock up as time goes on... Excellent choice of knife BTW!

    While the lock may lose some small amount of it's springiness over time, the lock face wears faster so as the lock face gets worn down, the further to the right it will travel. Most of the strength of the lock comes, not from how strong it is laterally (side to side), but along the axis of the blade.

    The lock tab is a spring. It wants to move all the way over to the right but it can't. Over time as it wears it moves further to the right.

    Thanks guys. One last question. What is the purpose of this semi circle indention (circled in red) it seems to have no purpose. I would expect such an indention for the back of the tang? to sit in when fully open, but instead it sits where the arrow is, a slight wear mark there already. Normal?

    The circled indentation is just a space to make the transition from the lock face to the back of the tang. The back of the tang is flat and the lock surface is ground precisely, so it makes sense to separate the two since they have different geometries. As for the arrow, mine also has that small indent. It's where the back of the tang rests against the stop pin, which stops the blade from rotating further open. The blade gets wedged against the pin and the lock face when open. By having two surfaces of contact, you reduce up and down blade play.

    Probably a indexing mark of some kind, used either in finishing the blade, or during assembly of the knife. No purpose for the end user. The other mark is where the blade tang contacts the stop pin when the knife is open. It might even come off if you rub it with a q-tip.

    I see, thanks. There is no indent where the arrow is on mine, just a surface wear mark from it hitting the stop pin I suppose.

    Thanks - You guys are great. I have this problem...every time I get something nice the OCD kicks in and I pry and pull until I find something wrong with whatever I bought. It's a vicious circle. Thanks for easing my worries - until I think of something else

    Taichung knives might be bad for you. You usually have to look very very hard to find something wrong with them. . Enjoy it!
