You can do it without using Blend. Simply add a slider in XAML page & open design view. Then right click on slider, open "Edit Template" menu and click on "Edit a Copy". So the default style of slider will be added in page's resource. Check out below given screenshot for it.

Now in style, you will see SliderThumbStyle. You can set thumb's template here. So I am giving you whole style with cylinder thumb having gradient effect.
