This lock was packaged under the "Helping Hand" brand which seems to be a brand for an American supplier of hardware to discount stores, the closest thing to a unique identifier for this model was the code "40010" printed on the bottom of the packaging (this is also the second half of the UPC so who knows what ID you might encounter it under).
Externally it looks like most other generic laminated steel padlocks with the obvious distinction of the keyway/plug face which is similar to the floating cap on a Master Lock 500. Here it is on the left beside examples of Master Lock's warded padlocks (L-R: 8596D, 500D, 510D) and their respective keys.
Notice that like the Master 8596, the key is only cut on one side and is fairly flat, this is because the keyway warding only allows the key to be inserted in one direction.
Despite the much simpler and more forgiving warding (compared to Master 500 and 510s) the mechanism can be manipulated in the same manner. Manipulation is actually even easier than the common Master Lock warded mechanism since this lock only has a single lever and latch (toe latching only). The lever sits near the end of the keyway and is normally engaged by the raised portion of the key between the tip and the last cut, the tip itself acts as a spacer.

Despite the apparent difference in the key design this lock can be manipulated with the same tools used against Masterlock 500 series locks without having to worry about manipulating a second lever. I find the wider of the two 't' shaped tools included in most warded pick sets works reliably, although I have found the longer tip and slightly greater width of the SouthOrd tool gives the best performance while the Peterson tool tends to slip off the lever more often.
The single toe latch is also ridiculously shim-able and will fall open with most medium diameter shims.
In conclusion, this is the type of warded padlock that everyone warns you about using for anything other than picking.
