I have slab molds which are not a problem to cut. The problem is getting the soap out of the mold. The mold is scored, so lining it would defeat the purpose. If I had one of the specialty molds like from Upland, then it would be a different story. I like the versatility of a log mold. If it is custom made, you could make it deep enough so that you could pour 2 lbs, 4 lbs or 6 lbs using the same mold, with difference being varying soap heights.
