What are the dimensions and weight of the SOG Kiku folding knife?

The SOG Kiku weighs 6.6 ounces and features a 3-inch blade, making it a compact folding knife designed for one-handed use.

The SOG Kiku XR utilizes a modified tanto blade made from CTS XHP steel, which provides a balance of hardness and wear resistance. While the blade measures 3 inches, the overall footprint is kept small by the use of a linen micarta handle, a high-density material that maintains a consistent feel regardless of moisture. We selected this model for our comparison because it offers a high lock strength of up to 1,500 pounds of force. For a tactical knife buyer, knowing the exact weight and blade length is critical because a blade that is too long may exceed legal carry limits in certain jurisdictions or fail to deploy quickly in a high-stress grip. Because the SOG Kiku uses an XR lock rather than a standard liner or frame lock, the handle remains slim while maintaining structural integrity.

What to Check Before Buying the SOG Kiku

Before purchasing this folding knife, verify these specific technical details to ensure it meets your requirements.

• Confirm the local legal restrictions regarding 3-inch modified tanto blades in your specific city or state.
• Verify if the 6.6-ounce weight, which includes the integrated clip, fits your preferred pocket balance.
• Check if the blade thickness is compatible with your current sharpening stones, as some high-hardness steels require specific grits.
• Confirm the deployment method—thumb hole, XR lock, and kick—matches your preferred one-handed opening style.

SOG Kiku Size and Weight Comparison

The SOG Kiku sits in a category of compact folding knives, which are pocket-sized tools designed for quick access and versatile cutting. If you require a larger blade for heavy-duty wood processing or a longer reach, you should look for options with a blade length exceeding 3 inches. Conversely, if you prioritize a minimalist profile over the XR lock’s mechanical complexity, you might consider options with simpler locking mechanisms that offer a different weight distribution. The SOG Kiku is designed for those who need a durable, one-handed opening tool that prioritizes a compact footprint without sacrificing lock strength.
