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.

Why does a blade sink on soapy water?
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 a steel razor blade float on water yet steel is denser than water?
Razor blades and paper float in water because they are both less dense than water. They are able to displace an amount of water equal to their own weight before they are completely submerged, enabling them to float.
Why a razor blade and paper clip float in the water?
it is due to the surface tension of water. due to the inter molecular forces present in between the molecules of water, the surface of water behave as a stretched membrane. blade and paper clip do not exert enough force to pierce the surface of water. so they flot over the surface of water.
Why does metal NOT float on water?
If the proposal is to float the metal on water, most metals won't float. That's because most metals are more dense than water and will sink. Note that this proposition sets aside any reaction that might occur between the metal and water. This is because there are some metals that react with water, and some react violently. See the link below to the related question about the metals that will float on water. There aren't many of them. If the metal you are considering isn't on the list of metals that willfloat on water, then it won't.
