Details: Dont be fooled by the imitations. The Blade Scale from American Weigh is the original pocket scale with a retractable backlit display. Now the Blade Scale comes bundled with an extra large expansion tray and carrying pouch to hold everything. With a 10 year American Weigh Warranty and such a low, low price, it only makes sense to choose the original Blade Scale. Weigh as much as 650 grams to as little as .1 grams.
