Noting that this work is already on the mainsite here: http://www.scp-wiki.net/scp-3238 and has received feedback.
OP, this is… pretty boring, so far as the object goes. Stuff like:
When SCP-XXXX is used to cut something, it doesn't cut, the first layer of the substance is untouched and any material between it gets severed to the molecular level, the effect stops once it reaches the last layer with it also doesn't seem to affect.
is hard for a reader to believe that the Foundation figured out on their own. Keep in mind that as the author, you know the entire story, but the Foundation needs to have discovered what it knows about the SCP object through observation and experimentation. You'll need to convince your reader that someone with no prior knowledge whatsoever of the anomaly managed to somehow figure out (not magically know!) all the information you've got in the article.
Furthermore, your containment is kind of ridiculous… a one-meter cube box is wholly unnecessary, and would also be an enormous pain to use as storage given how small the knife is. Don't refer to SCP objects as SCPs in a document; that's casual wording. If this thing needs to have security guards pointing weapons at D-Class during testing, don't let D-Class test it. The titanium test is unnecessary because titanium is not a magical metal or anything and people downvote for unnecessary mentions of titanium for rule-of-cool narrative.
Ultimately a knife that cuts weird isn't really interesting or much of a new sort of approach. We delete stuff like that off the mainsite maybe a couple times a month, since knives and swords and other sharp things are pretty commonly attempted by new members who just want to write something cool.
I recommend getting the base idea polished up in the Ideas and Brainstorming forum before you try fixing the draft. Go to that forum, post a quick summary of the concept you want to write up (don't link the draft unless someone asks), and reviewers there can help you.
