Tennessee River Valley Knife Association trademarked Marble's in 1990 in trademark classification 8. The Marble's Arms Corporation in Gladstone, Michigan had not produced knives since 1977 and had not renewed the trademark since 1948. Thusly, the trademark expired. TRVKA produced several thousand knives under their trademark. Marble's Arms Corp was sold to CRL, Inc. in 1994 and TRVKA sold the Marble's trademark for cutlery to CRL, Inc in 1996. The firm now operates under the name Marble's Arm CRL, Inc. As of August 15, 1996, their plans were uncertain as to what they were going to produce in knives.

In late 1997 the new owners of Marbles started making more knives at their Gladstone, Michigan facility. The first ones were made using the old knife blades and parts that were left over from the old days. This group of knives are all fixed blades. Most of the old parts have been used up, and they are not making any more pocketknives as of 1997. They are using custom rolled 52-100 high carbon steel in the current knives.

Looks like Marble knives are no longer made in the USA as of Sept. 2009.
