Limbo of the Lost "Metal Cutters"
The source image has been used 'as is'.
Note that the description is incorrect; these are wire cutters - sheet metal cutters are an entirely different tool.

Source image as found on istockphoto.com through images.google.com, search terms: old wire cutters, result 4 on page 1.
Note that this is a stock photo and its use, if licensed, is perfectly valid. However, traces of some of the watermark lines may appear in the LotL image; JPEG compression in the image referenced here make this difficult to identify with absolute certainty.

Limbo of the Lost "Glass Orb"
The source image has been scaled non-uniformly, pasted onto a background and given the typical Limbo of the Lost 'glow'.

Source image as found on www.home.no/t-o-k/ through images.google.com, search terms: glass ball, result 10 on page 12.
This is an original image created by Tor Olav Kristensen.

Limbo of the Lost "Apron"
The source image has been scaled non-uniformly. The brand name, KUNY'S, is still faintly visible.

Source image as found on woodcarvingsupplies.com through images.google.com, search terms: apron, result 13 on page 8.
Note that this image appears to a scan from an unidentified printed catalog.

Limbo of the Lost "Cooks Hat"
The source image has been edited to remove the woman's head, the inside of the hat was then apparently painted in.

Source image as found on virginkeywest.com through images.google.com, search terms: cook's hat, result 4 on page 1.
Note that this is not the original image either, given the oddly cut-off text.

This particular item is from the NVidia 'Smoke Box' tech demo. The exact image is not present on the NVidia, or any other easily-found, site and may have been screencapped by the Limbo of the Lost developers from the realtime demo.

Limbo of the Lost "Candle"
The exact source is unclear as this is a common product resold through various (online) stores. If the stock image of the product was used, then at least what appear to be a sticker on the product has been painted out.
Later on in the game, a red candle is introduced; this is the same image with a colorized candle and what is supposed to look like wax having melted to the holder's basin colorized in as well.

Source image as found on ancientrites.co.uk through images.google.com, search terms: black candle, result 12 on page 6.

Limbo of the Lost "Metal Bar"
The source image has been rescaled, sides were added by cloning, and the right-hand end was painted in.

Source image as found on genchem.chem.wisc.edu through images.google.com, search terms: metal bar, result 5 on page 1.
Site cites as source "Journal of Chemical Education - Vol. 65, 1988, page 69"

Limbo of the Lost "Pair of Metal Tongs"
The source image was rescaled.

Source image as found on amazon.co.uk through images.google.com, search terms: metal tongs, result 2 on page 1.
A pair of metal tongs from the "Farringdon Collection".

Two Google Image results appear to depict the same model, but in different lighting and angle situations.

Limbo of the lost "Key"
This key is a common depiction of a skeleton key.

One particular Google Image result appears to depict the same model, but the lighting is slightly different.
