This review looks at a 3-pack of universal 9-inch edger blades marketed for Craftsman walk-behind edgers, along with Mclane 2059, Power Trim, Tru-Cut and King lawn edger models. Craftsman lawn edger blades are a common replacement item, so the real question is whether this generic set fits your machine, cuts cleanly and costs less than an OEM part. It suits owners with a compatible older Craftsman or similar edger who need a set of spare blades. It is less suitable for anyone who needs an exact factory part number, a specific blade shape for a specific model, or a blade that will fit a machine without checking the center hole and mounting pattern first.
3 Pcs Universal 9" x 9" (1/2 inch Hole) Edger Blade, 3-Side Edger Star Blade for Craftsman Walk Behind Edger, Mclane 2059, Also for Power Trim Edgers Tru-Cut Edgers King Lawn Edgers
Product Overview
This product is a three-piece pack of replacement edger blades, sized at 9 inches by 9 inches with a 1/2-inch center hole. The blade has three cutting sides, which is why the listing calls it a “3-side edger star blade.” It is aimed at people repairing or refreshing a walk-behind or power-trim style edger, where the blade is the part that does the cutting along the sidewalk, driveway or bed line.
The listing names several machine families: Craftsman walk-behind edgers, the Mclane 2059, and power trim edgers from Tru-Cut and King. Because these are generic replacements rather than factory-branded parts, buyers should confirm the center hole, overall diameter and mounting arrangement against the blade they are removing before ordering. A blade that looks similar can still differ in hole size or the position of its drive tabs.
Blades like this are usually bought as wear items. Cutting edges dull, nicks develop from rocks and curb edges, and a bent or cracked blade can cause vibration. Replacing the set is often more practical than sharpening a three-sided star blade, since the geometry is harder to restore evenly by hand.

Pros & Cons
Pros
- Three blades in one pack, so you have spares on hand for a season of edging.
- The 9-inch size and 1/2-inch center hole match a common replacement profile for several edger brands.
- Three cutting sides give more usable edge per blade than a simple two-sided design.
- Universal listing covers multiple machine families, which helps if you own more than one brand.
Cons
- Being universal, it is not a factory part, so fit depends on your exact model matching the stated dimensions.
- The listing does not confirm blade material or thickness, which affects durability on rocky or root-heavy edges.
- Owners who need a guaranteed OEM match will need to look elsewhere.
- Installation still requires checking balance and hardware, since generic blades can vary in tolerance.
Performance Analysis
Because the listing does not publish cutting metrics, performance has to be judged from the specifications and from the general behavior of this blade type. A 9-inch blade with three cutting faces is designed to spin through turf and slice a vertical cut into soil, so the practical result depends on three things: how sharp the edges are, whether the blade is balanced, and whether the mounting is tight.
Owners of replacement blades in this category often report that a fresh blade cuts cleanly through sod on the first few passes and produces a crisp vertical face. The most common complaints, based on general patterns with generic edger blades, involve fit (a hole or mounting tab that does not seat perfectly), vibration from slight imbalance, and dulling after contact with gravel or landscape stone. Those issues are not unique to this product, but they are the points to check on arrival.
For best results, mount the blade with the manufacturer’s washer and bolt arrangement, tighten evenly, and spin it by hand to check for wobble before running the machine. Keep the blade away from curbs and stones, and expect to replace or re-sharpen sooner if you edge in hard, rocky soil. The three-sided design also means the cutting edges wear unevenly over time, so rotating or inspecting all three faces is worthwhile.

Who Should Buy This Product?
This set makes sense for owners of a compatible walk-behind or power-trim edger who want spare blades on hand and are comfortable confirming dimensions before installation. It is also a practical choice for someone with a mix of machines who needs one generic size that fits several brands.
You should skip this product if your machine requires a specific part number, if you have a model that uses a different hole diameter or blade diameter, or if you want a blade whose material and hardness are clearly documented. In those cases, an OEM blade or a model-specific replacement is the safer purchase. If you are unsure which blade your edger uses, check the existing blade and the owner’s manual first, and see Craftsman Lawn Edger Parts: How to Find, Identify and Replace Them for identification tips.
Buying Guide
Before buying any replacement edger blade, measure the blade you are removing. Check the overall diameter, the center hole, and the position of any drive tabs or notches. A difference of even a few millimeters in hole size can cause vibration or prevent the blade from seating.
Next, decide between a universal blade and an OEM blade. Universal blades are often the more economical choice and widely available, but they require more care in fitting. OEM blades remove fit uncertainty but may be harder to find for older machines. Both can work well if the dimensions match.
Consider blade shape as well. A three-sided star blade produces a different edge profile than a straight two-sided blade, so if your current blade is a different style, switching may change how the edge looks.

FAQ
Will these blades fit my Craftsman edger?
They are listed for several Craftsman walk-behind edgers, but fit depends on your model. Measure your current blade’s diameter and center hole, and compare them to the 9-inch and 1/2-inch specifications before ordering. If the dimensions match and the mounting arrangement is the same, the blade should install normally.
Are these genuine Craftsman parts?
No. The listing describes this as a universal replacement for several brands. For a factory-branded blade, look for the CRAFTSMAN-marked replacement listed separately.
What does a three-side edger star blade do differently?
A three-sided design presents three cutting faces, so each blade can offer more usable edge before it needs to be replaced or sharpened. The geometry also affects how the cut looks, so the edge may differ slightly from what you got with a two-sided blade.
How do I install a replacement edger blade safely?
Disconnect the spark plug wire or remove the battery before working on the blade. Use the correct wrench, reinstall the washer and bolt in the original order, and tighten evenly. Spin the blade by hand to check for wobble. If you are unsure about the procedure, consult a qualified small-engine technician or the equipment manufacturer.
How often should I replace edger blades?
There is no fixed schedule. Replace or sharpen when the cut becomes ragged, when the edge tears turf instead of slicing it, or when the blade is nicked, bent or cracked. Edging in rocky soil will shorten blade life.
Can I sharpen these blades instead of replacing them?
Many edger blades can be sharpened with a file or bench grinder, but the three-sided shape makes even sharpening harder. Remove the blade, keep the original angle, and balance it afterward. If you cannot maintain the geometry, replacement is the safer choice.
Do these fit power trim edgers and other brands?
The listing names Power Trim, Tru-Cut and King edgers as compatible families. Confirm the center hole and diameter on your specific machine, since model variations within a brand can differ.
Is this blade suitable for all lawns?
It is suitable for typical residential edging in most turf types. For very rocky, root-heavy or heavily compacted soil, expect more wear and consider a more durable blade material if available.
Final Verdict
Worth buying for the right owner
This three-pack of 9-inch, 1/2-inch hole universal blades is a reasonable choice for owners of compatible Craftsman, Mclane, power trim and similar edgers who want spare blades and can confirm fit before installation. It is less suitable for anyone who needs an exact OEM part or a blade whose material is documented. Measure your existing blade, confirm the mounting, and balance it before running the machine.
