You can float a razor blade on water due to the 'Surface Tension' of the water. This is the tendancy of the water molecules to stay tightly together, which is why a water drop forms a 'hump' on a surface. Soap is a 'wetting agent', or surfactant. When you add soap to the liquid, the surface tension is drastically reduced, and the water molecules 'flow' around objects, like the razor blade. So, it sinks.

Why does razor blade float?
In case of a razor blade, the surface area of the blade increases as compared to a steel block of probably the same mass kept in water. Pressure is inversely proportional to area. Hence less pressure acts on the blade in downward direction resulting in floating of it on water surface. Bouyant force exerted on the body increases than weight acting downwards causing the floating.

Sunken ships sink because they take on water, increasing their overall weight and causing them to sink below the water's surface.
