No any tricks. Very easy. Check this video: https://www.youtube.com/watch?v=qkP2au2aLRY&feature=youtu.be

I struggled with it too and gave it to my husband. He detached it easily so it isn't the blade; it was me. He thinks he might have pushed it in a little before twisting. Good luck. It really works great when it works!

Haha, a common problem if your not familiar. There is a metal tab that runs along the inside of the handle. Push it to the left then slowly and carefully close the blade forward and shut

First find the black button next to the handle,push it in and hold it locks the blade into place, then lossen the blade and replace the blade same way as well

If you start to open the blade with your thumb, about half way open the spring will assist with the rest. I usually give the spring an assist by flicking my wrist to "snap" the blade into place. It doesn't always lock with just the spring.

There is no lock on the blade height. I haven't noticed any movement up or down once the blade height is set.

My husband bought this knife. He said "no". The blade will snap into the open position, but it does not "lock" like a traditional lock-blade knife does. Hope this helps.

I noticed on mine that I sometimes had to manually push the blade a bit further out to get the lock to release properly on occasion.

You don't have to move anything. Put the blade in the slot so that the hook is over the clasp, it will be at an angle to the handle. Then holding the back of the blade give the handle a sharp whack on the floor or whatever and it will lock into place. Same goes for taking the blade off only in reverse

Make sure the attachment is pushed all the way in, then turn the locking ring at the top of the handle. It can be difficult to turn!

Set it in place and push the yellow button. I often have to wiggle it a little to get it to lock in and start cutting.

Maybe, but you have to depress the lockback and hold before putting closing pressure on the blade. Sometimes the lockback switch is stiff and it needs some oil and working in a number of times. I hope this solves the problem. This is a Great knife!!

Take a screw driver and slightly bend the metal flange in between the farm so that it aligns with the blade when open. If that doesn't work I gues you need trend it back

On my unit the 3 screws that hold the blade will not release. I have tried both directions...thinking they may be reverse thread...still no movement.Tried some penetrant...no luck.Any thoughts

Never had this problem. I'd check to make sure blade is engaged and take battery out & put it back in. May have just jiggled loose.

There is a thumb notch along the spine of the handle that you can flick, making the blade jump out quicker. However, on this knife, it doesn't flick out to a locking position like most other assisted open knives. Its still a good blade though.

There is a thin piece of metal that slides over to lock the blade in the open position. To close you will slide this thin metal lock back to the side, out of the way for the blade to close. It is located in the index finger groove of the handle. If the knife is open and you look at the handle where the blade goes when closed, you will see it in the way of the blade closing. Just push it over out of the way and the blade will close easily.
