Westcott Office and School Ruler

I'm a bit disappointed with the quality of this ruler. I bought this one because I own a couple of plastic rulers and I needed something steadier and with some grip to draw lines with ink pens and paintings, so this seemed ideal. The steel is good, but also feeble and wobbly, not strong enough. This being the case, the ruler is not steady enough. Also, for whatever reason, the lines don't come up clean. It doesn't help that the cork at the base has some edge, as it doesn't cover the full ruler belly and I think contributes to the wobbliness. It would not use this with paints or ink pens, just to measure or use with pencil.
