Find Common Words In Cells And Create New List

I have a spreadsheet of part #'s, descriptions, manufacturer names, and manufacturer part #'s. (It's a list of the inventory in my warehouse). Each row contains information for just the item in that row. Row 2 references another part in my warehouse, row 3 yet another, and so on.

Many of the parts have more than one potential manufacturer and part #, (meaning that any of those manufacturer's part #'s are basically the same tool; just different brands. At one time we may get a shipment of one, at other times we may get a shipment of another). For example, a screwdriver may be listed like this:

Part # 1234 screwdriver, mfg Snap-On, part # 456, mfg Stanley, part # 789, mfg Mac Tool, part # 439.

Then further down the list, there may be another part listed like this:

Part # 9980 wrench, mfg Stanley, part #741, mfg Snap-On, part # 852, mfg Proto, part # 369.

If you can imagine that data across the cells of a spreadsheet row, notice how the mfg name 'Snap-On' was the first mfg name on the screwdriver, but it was listed as the 2nd mfg name on the wrench.

So, here's my question: I want to be able to group all of the items made by any one manufacturer together in a new list. If all of the manufacturer names were in the same column, I could simply sort the list by that column, but since I've got thousands of rows with the mfg name I'm looking for in different columns on different rows, I thought maybe a macro could search each row for the word I'm looking for, then if found, take the whole row and copy it to a new worksheet. So the end result would be, If I wanted to see all items of which Snap-On is an acceptable supplier, I could get a list of all potential Snap-On items grouped together.

I'm sorry this is so long. I may have over-worded this and it may not be too clear. I could email an example of the spreadsheet if anyone needed more info to figure out what I'm looking for and was willing to take a look at it.
