It's a Factory(?) set of surgeon knives/gloves that allow for the manipulation/animation of blood.
Okay, this does not feel Factory at all. Hell, it doesn't even feel logical. Why would anyone make this? There's literally no point or interesting thing about this, it's just… weird. And not weird in a "oh, interesting" way, but weird in a, "well, that's not normal, but so what?" way. This base idea is fairly boring; you need to think of some kind of hook or twist for this.
Special Containment Procedures
Any hostile incidents of SCP-XXXX are to be terminated immediately.
How do you terminate an incident?
These procedures could use more meat. You can include what not to do with the skip, any special procedures with handling it, how to test it, etc.
"The Factories Blood Sculpture Set"
I imagine that's supposed to be "The Factory's"
Upon making an incision into the skin with the scalpel, blood will emerge as a substance similar to that of 'goo'.
"goo" is not a substance. If you're trying to say the liquid is very thick and slow moving, you could say something along the lines of it having a high viscosity.
Incisions made cannot exceed 3 cm to allow SCP-XXXX's anomalous properties to take effect. Incisions made within the limit will be completely absent of pain and will heal seconds after desired amount of blood is drawn. Incisions made exceeding 3 cm in length will have an effect similar to that of a normal scalpel, leaving an open wound as opposed to healing instantaneously.
You start three sentences in a row with the same two words. Please vary that a bit.
The gloves are capable of maneuvering blood through the air by gestures of the fingers.
Upon molding the blood into any shape, the gloves can animate the shape.
What's the point of that?
The first instance of SCP-XXXX was found and recovered from an abandoned factory located in ████, Georgia, in 1986. Newspaper articles described events such as "Maroon Monsters Attack ████!" Mobile Task Force Delta-5 was promptly dispatched to locate the source of the anomaly.
This doesn't really add much to the article. It could be removed completely and the article wouldn't really be affected.
