Microtech H.A.L.O.
Assembly
You know you shouldn't take apart your
Microtech H.A.L.O. knife -- it's got a lifetime warranty if anything is
wrong, and they are built so well they aren't going to break. But
if you must -- you must see what is inside -- or clean out all the chocolate
syrup you got in it -- a tip or two.
This information is from me, not endorsed
by Microtech in any way. I do not warrant it in any way, shape, or
form. If you are not qualified to work on knives of this type --
don't. Microtech and H.A.L.O. are likely registered trademarks.
Parts List
(8) Cap-Head Screws (all the same)
(1) Unlock Button
(1) Unlock Button Spring (under it)
(1) Blade with two pressed in pins
(1) Bottom Side Plate (with detents)
(1) Top Side Plate (with Unlock Button
hole and track for Blade Retractor)
(1) Blade Retractor
(1) Main Spring
(2) Spring End Caps
(1) Spring Rod
These are all the parts you will have
when you remove the 8 screws holding it all together. The pins could
be pressed out of the Blade if you were deluded, and the detents (2) and
their springs (2) can be removed from the Bottom Side Plate by driving
out the retaining pins (2) from the outside.
When you take this knife apart the Main
Spring, Spring End Caps, and the Spring Rod will
fly out across the room unless you are very
careful to capture them. The
entire challenge to working on this knife, from assembly to disassembly,
is to not lose these pieces by letting them fly off to parts unknown.
Be careful, planned, and deliberate in your actions. You might
even want to work with your hands and all the parts inside a large, clear
plastic bag.
Reassembly
-
Lay the Bottom Side Plate down in front of
you.
-
Install the Blade in the retracted
position -- the circular cutout on top of the blade should line up with
the hole for the Unlock Button. I put a drop of oil on each side
of the Blade in the area where the pins are pressed into it.
-
Install the Unlock Button and Unlock Button
Spring. I use a drop of oil on both sections of the Unlock Button.
-
Note the rectangular area cut-out in the blade
to the left, cut out in the Bottom Side Plate to the right, about 1" overall.
This is where you will be installing the Spring Assembly.
-
Fully insert the Blade Retractor into the
Top Side Plate. I put a tiny drop of oil on each Blade Retractor
edge.
-
Get the screws ready along with an Allen wrench
to install them.
-
Now comes the tricky part.
-
Put the Spring Rod into one of the Spring
End Caps
-
Start feeding and capturing the spring over
the Spring Rod and into the Spring Cap. Don't let any of these
parts go flying and lose them!
-
You should be able to gather up the whole
Spring over the Spring Rod. When you have, carefully slip the second
Spring Cap over the top. You should now have the entire spring held
within the two Spring Caps. Hold this Spring Assembly by its ends
very
carefully, don't let go.
-
(The previous 3 steps might be easier if you
take the guts out of a ball-point pen and use the tube as a guide to stack
and compress everything. This worked for me, but I don't have the
skill to pass on all the details in print.)
-
Slip the Spring Assembly into the cut-out
area in the Blade and Bottom Side Plate. Hold it down in place with
a fingertip while you pick up the Top Side Plate and carefully install
it. The two detents will snap as the Top Side Plate is pushed in
place.
-
Immediately install all 8 Screws almost tight.
-
Cycle the knife several times to make sure
all is well.
-
Fully tighten all the screws.
