The OmniBlend 1.5L Tamper Tool is designed specifically with a security flange (the collar near the handle) to ensure it can’t reach the blades while the lid is secure. Tips for Proper Use:

• The “Hole” is Key: Never use the tamper without the lid in place. The lid acts as the safety gate that prevents the stick from hitting the blades.
• Thick Mixtures: It’s your best friend for making nut butters, thick smoothies, or frozen sorbets where air pockets (cavitation) tend to form around the blades.
• The Technique: Instead of just stirring, use a firm downward motion toward the four corners of the jar to push unblended ingredients back into the vortex.
