Peaky & Spike (V-Block) blocks have similarities to Flying Geese Units (center body with two wings), but the angles are not 45 deg, so the construction & trimming are slightly different.
The name "Peaky & Spike" was coined by a renowned quilter Doreen Speckmann. She felt each piece of the unit had a character - the center he called "Spike", and the outer wings she called "Peaky".
