Learn how this precision knife sharpener brand used a product recommendation quiz to educate customers, simplify purchasing decisions, and dramatically increase their average order value.

Wicked Edge is a leading seller of precision knife sharpeners and accessories, known for their innovative approach to blade sharpening. Their products differ significantly from traditional sharpening methods, offering precision and repeatability that knife enthusiasts love.
With nearly 20 years of experience in the industry, Wicked Edge has built a reputation for quality and innovation. However, their unique products required customer education to help shoppers understand the value and find the right system for their needs.
Wicked Edge's products differ significantly from other sharpening solutions in the market, making it difficult for new customers to understand their functionality and determine the best model for their needs. This learning curve created a barrier to purchase, affecting the company's conversion rates.
To educate customers and simplify their shopping journey, Wicked Edge and Tako Agency developed a product recommendation quiz using Octane AI. The quiz was designed to assess customers' needs and suggest appropriate products, effectively reducing confusion and building confidence in their purchasing decisions.
Tako Agency used Miro to create a detailed flowchart, visually mapping out the customer journey along each branch of the quiz. This careful planning ensured customers received personalized recommendations based on their specific sharpening needs and experience level.

One of the most impactful features was Octane AI's "Add All to Cart" button. This allowed Wicked Edge to create pseudo-bundles without changing their inventory management system or creating new SKUs. When customers receive their recommendations, they can add all suggested items to their cart with a single click.
Questions designed to understand customer requirements, knife types, and sharpening experience level.
Two questions dedicated solely to collecting customer data for personalized follow-up marketing.
Pseudo-bundles that add recommended items as individual line items without requiring SKU changes.
Each quiz answer passes through as an individual data point for nuanced email segmentation.

Wicked Edge manufactures precision knife sharpeners—tools that require a significant understanding to use effectively and to choose the right model. Unlike simple kitchen accessories, their sharpening systems represent a real investment (with an average product price well above typical e-commerce items) and serve a dedicated audience of knife enthusiasts, chefs, and professionals.
The challenge? Even customers who recognized the value of precision sharpening often struggled to determine which Wicked Edge product was right for them. The product line includes multiple sharpener models, each with different features, price points, and accessory compatibility.
“Our products are unique. Customers come to our site interested, but they often don't know where to start. We needed a way to guide them through the decision-making process.”
–Wicked Edge Team, on their challenge
Working with Tako Agency, Wicked Edge built a comprehensive product recommendation quiz using Octane AI. The quiz was designed not just to recommend products, but to educate customers along the way—helping them understand what factors matter for their sharpening needs.

Tako Agency took a methodical approach to quiz design. They used Miro to create detailed flowcharts, mapping out every possible customer journey through the quiz. This ensured that no matter what answers a customer provided, they would receive thoughtful, relevant recommendations.
The quiz asks customers about their sharpening experience level, the types of knives they want to sharpen, and their specific goals. This information helps Wicked Edge provide recommendations that truly match customer needs—not just push higher-priced products.
“The quiz doesn't just ask what customers want—it helps them discover what they need. That education component is what drives the higher AOV.”
–Tako Agency, on the quiz strategy
One of the most impactful features of Wicked Edge's quiz implementation was Octane AI's "Add All to Cart" functionality. This feature allowed them to create pseudo-bundles—recommended product combinations that customers can add to their cart with a single click.
Here's why this matters: Wicked Edge's sharpeners work best when paired with the right accessories—diamond stones, strops, angle guides, and more. Before the quiz, customers often bought just the base sharpener, missing out on accessories that would significantly improve their experience.
With the quiz, Wicked Edge could recommend complete setups. Customers who needed aggressive edge restoration would see diamond stone recommendations. Those interested in mirror finishes would see progression kits and strops. And because customers could add everything to cart at once, they were far more likely to purchase complete solutions.
The "Add All to Cart" feature works without requiring inventory management changes. Each recommended item is added as an individual line item, meaning Wicked Edge didn't need to create bundle SKUs or adjust their fulfillment process. It's the best of both worlds: customers get a bundled experience, while the backend stays simple.
Beyond immediate conversions, Wicked Edge uses quiz data to power sophisticated email marketing campaigns. Each quiz answer passes through to Klaviyo as an individual data point, enabling highly segmented user groups and personalized messaging.
This integration allows Wicked Edge to:
“The zero-party data from the quiz has transformed our email marketing. We're not just sending generic newsletters—we're sending personalized recommendations based on exactly what each customer told us they need.”

Wicked Edge's success demonstrates several important principles for brands selling complex or high-consideration products:
The introduction of the quiz led to remarkable outcomes, significantly boosting both AOV and conversion rates.
Customers who took the quiz had an AOV of $727.30, compared to the store's overall AOV of $450.14.
Quiz takers converted at 3.6%, more than double the store's overall conversion rate of 1.5%.
Within the first six months, Wicked Edge saw a 28% increase in revenue attributed solely to the quiz.
