Chris Christensen Big G or Original Oval Pin Brush?
A documentation comparison of two real brush ranges, with the suitability question left to the right professional.
What is being compared
Two brushes from the same maker sit at the center of this comparison: the Chris Christensen Big G Slicker Brush and the Chris Christensen Original Series Oval Pin Brush. Both come from a manufacturer that builds several brush families for coat work, but these two use different tools entirely: one is a slicker, the other a pin brush.
The Big G is listed as a slicker brush with stainless steel pins measured at 27mm, and it’s sold in three sizes: Baby G, Medium Big G, and Large Big G. Each size pairs a specific head dimension with a stated use, ranging from hard-to-reach spots to full-body work on larger dogs.

The Original Series Oval Pin Brush is a separate product line built around a Beechwood body and an oval head shape. It’s sold in three pin lengths (20mm, 27mm, and 35mm), with each length tied to a different coat depth on the product page.

The core distinction is construction, not just size. The Big G page describes long, bent stainless steel pins in a flexible cushion pad, an extreme curved back and an extra long handle. The Original Series page describes stainless steel pins that are ground and polished at the tips, set in a durable, firm cushion with one air vent hole, on a Beechwood body. Pin length is not the dividing line, since the Big G’s pins are 27mm and the Original Series is sold from 20mm to 35mm. The cushion, the tip finish and the pin shape are.
Both product pages list a 6-month manufacturer’s warranty and note Prop 65 compliance, details worth confirming directly on each listing before you buy.
Why the model details matter
Pin length and brush size aren’t cosmetic specs. They’re the numbers each product page uses to map a model to a job, which makes them the part of the listing worth reading before the description.
On the Big G page, the maker states the brush carries “30% more pins than the Big K brushes.” Read that alongside the same page’s slicker chart, which is more specific than the marketing line above it: both brushes carry 27mm pins, and the chart puts the Big G against long coats and the Big K against long and dense ones. The three Big G sizes each map to a stated task: the Large Big G (8″ length) is listed for body work, the Medium Big G (7-3/8″ length, 2-3/8″ x 3-3/4″ head) for legs, columns and poms, and the Baby G (same 7-3/8″ length but a square 2-3/8″ x 2-3/8″ head) for hard-to-reach areas. The two shorter brushes have the same listed overall length and different head dimensions. Use the maker’s stated tasks as questions for the groomer who knows your dog’s coat, rather than assuming the dimensions establish the right choice for every body area.
The Original Series pin brush works on a different logic. Its three pin lengths are tied to coat depth on the product page, and the mapping is stated plainly: 20mm for short coats, 27mm for medium to long coats, 35mm for long thick full coats. That’s the maker’s own recommendation and the whole of what the page offers on the question. It does not say what happens if you pick the wrong one.
Neither brush’s size or length chart substitutes for an assessment of the individual coat in front of you. The maker’s own coat-length guidance is a starting point, not a guarantee that a given size will suit every dog described as “long-coated” or “short-coated.” Breed, coat condition, and how matted or clean the coat is at the time of brushing all factor into whether a listed size is the right fit, and that judgment sits with the groomer or owner, not the spec sheet.
Compare the job in your routine
These two brushes are built for different stages of coat work, and the product pages support that split directly. The Big G is described as a tool “to make grooming easier and faster when working with dense coats,” with bullets that read “Use to fluff and shape dense coats” and “Removes thick undercoat.” The Original Series pin brush is described more broadly, as suited to “all coat types” and useful for “effective and efficient detangling.”
That difference suggests a rough division of labor: the Big G leans toward fluffing, shaping, and undercoat removal on long or dense coats, while the Original Series pin brush leans toward general detangling and glide-through work across a wider range of coat types. Neither product page claims the other brush’s job as its own.
| Criteria | Big G Slicker Brush | Original Series Oval Pin Brush |
|---|---|---|
| Pin type | 27mm stainless steel, bent | Stainless steel, ground and polished tips |
| Sizes/lengths offered | Baby G, Medium, Large | 20mm, 27mm, 35mm |
| Body material | Not stated on product page | Beechwood |
| Stated best use | Dense, long coats; undercoat removal | All coat types; detangling |
| Price (as listed) | $55.50 to $62.50 | $37.00 to $45.00 |
| Warranty | 6-month manufacturer’s | 6-month manufacturer’s |
Choosing between them as a first brush or an added tool is an organizational decision, not one the product pages settle outright. One possible routine uses a pin brush for general detangling and a slicker for finishing dense areas.
Treat performance language as a claim
The Big G product page describes its intended function as making grooming easier and faster. The Original Series product page describes its intended function as effective and efficient detangling.
The Big G page states the brush has “30% more pins than the Big K brushes.” That’s a comparative figure between two products in the same maker’s lineup, not a measurement against pin brushes or against any other manufacturer’s slicker. It doesn’t tell you how the Big G performs against the Original Series pin brush on any specific coat.
The Original Series product page states that its pins are ground and polished for comfort and describes them as gliding through the coat easily.
Both pages are the manufacturer’s own store, which matters for how to read them. Specifications and pricing come straight from the maker, which is the best available source for those. The descriptive language around them also comes from the maker, and it is selling. Neither page is a substitute for veterinary or professional grooming judgment about what a specific dog’s coat needs, and neither claims to be.
When a product description uses words like “perfect for” or “great for,” treat that as the manufacturer’s positioning of the product within its own catalog. It’s a useful signal for narrowing options, not a guarantee of outcome for an individual dog’s coat, condition, or grooming history. Reading spec sheets and marketing copy side by side, rather than treating either as neutral evidence, keeps the comparison grounded in what’s actually stated.
Check the purchase details
Price and stock vary by size, and both listings break out cost per variant rather than charging a flat rate. The Big G is priced at $55.50 for Baby G, $59.50 for Medium, and $62.50 for Large, according to its product page. The Original Series Oval Pin Brush is priced at $37.00 for 20mm, $39.00 for 27mm, and $45.00 for 35mm.
Check the selected size on the current listing before ordering. A listed range of sizes does not establish that every option is in stock.
Each product page states a 6-month manufacturer’s warranty and Prop 65 compliance. Neither page details what the warranty covers beyond that timeframe, so confirming the specifics directly with the manufacturer before purchase is a reasonable step if that matters to your decision.
The Original Series page also notes the brush is “crafted with quality materials in Germany,” a manufacturing detail specific to that product line. The Big G page does not include a comparable country-of-origin statement.
Before buying either brush, check the current price and size availability directly on the product page, since both can shift. Confirm the pin length or brush size against the coat you’re working with, using the maker’s own coat-length guidance as a starting point rather than a final answer.
If a specific dog’s coat presents matting, skin sensitivity, or another condition, that’s a judgment call for a groomer or veterinarian, not something either product listing is positioned to resolve.
