Question: Can I replace the tungsten tip??
Document: And I am in doubt... my first tests see it working but I had real difficulty making a mark on polished steel. Surprisingly the tip was slightly oiled inside its plastic cover, but for all I can see the tip may well be just steel, not tungsten carbide! The tip being replaceable and the packaging tamperable and tungsten carbide undistinguishable from other metals (?
Also, since it is only a small tip, it cannot be readily seen if it is indeed denser as tungsten carbide is, not without some more formal testing I cannot conduct! I have the impression that inscribing metal with it should be more free flowing and less literally scratching marks. I would return it but for the price it may be good enough even if I do feel dissappointed and doubtful. Tungsten carbide seems to be scarce and a special material so substituting it for plain steel may be temptful to some people!
Kinda hard to get excited over a carbide Scriber. The magnet on the end is a nice touch, but not sure just how useful it is with out being extendable. Seeing as Tungsten Carbide is brittle it would have been nice if General Tools had included a plastic cap to protect the tip. Think I'll try to scrounge one from one of my Exacto knives.....
This item was not expensive and it works both as I scribe when the pen is straight up and down and when it is at a slant. It seems to be staying consistently sharp, which is the reason I bought the tungsten carbide scribe. I am using this for adding detail to my glass etchings on wine bottles.
Great tool no problems! The tungsten really makes a difference when trying to scribe hardened metals. Worth the money !
Packaging is a plastic cover held by a staple to the printed cardboard so I have no guarantee of the product being new or not having been tampered with. I did not expect a detachable tip, which supposedly can be replaced, but a well integrated metal rod...
The magnet on the scriber is quite strong, and the scriber works excellent for scratching into glass, aluminum, and steel. I have not tested it on any other surfaces, but the tip seems to be holding up quite well and overall the product works great.
Nice scribe, good hard sharp tip. You must remember to tighten the tip-collet snugly or the tip will slip or fall out. The magnet is not super-strong, but I bought this for the scribe, not the magnet. Pocket clip is silly unless you have a pocket liner, or like holes in your shirt pockets.
Scribes well enough for my purposes. I'd describe the magnet as strong, but don't really need it. As mentioned in a recent review, the tip can be reversed for safer transport-storage -- problem is the tip collet turns very hard on mine, like it's grinding, as if the threads weren't machined well. So, practically, I can't take advantage of that feature -- it's so hard to turn I'll leave the tip out.
This carbide scribe is hard to beat as an Amazon $4.96 add-on. I use it mostly for hardwood layouts and occasionally metal, when i need the precision of a thin scribe line. The carbide tip holds up well. This scribe has a replaceable point that fits into a 1/8" collet, so the 88CM can also work as a  1/8" machinists pin vice in a pinch. This is not a Starrett quality tool, but for the price it's a great value.
Answer: yes
